Colin McDonnell 74b313e612 bump claude-opus alias to 4-7
anthropic shipped claude-opus-4-7 today; opencode also republished it.
point the "claude-opus" alias at the new version for both providers so
existing users get the upgrade automatically. openrouter hasn't
published 4.7 yet, so leave openRouterResolve at 4.6 as the BYOR fallback.

also clarify the latest-model snapshot comment: new model drops usually
just mean bumping the `resolve` on an existing alias, not adding a new one.

Colin McDonnell 2d1f1d33db replace suffix-based env filtering with default-deny allowlist (#543)
* replace suffix-based env filtering with default-deny allowlist

filterEnv() now only passes known-safe GitHub Actions runner/system/toolchain
vars plus user-configured allowlist entries to shell subprocesses. GITHUB_TOKEN
and GH_TOKEN are always blocked, even from the user allowlist.

adds envAllowlist field to repo settings with dashboard textarea UI (visible
only when shell isolation is enabled) and wires it through run-context API
to the action runtime.

* address review: blocked-name warning, JAVA_HOME prefix, stale waitlist copy

- setEnvAllowlist now strips BLOCKED_ENV_NAMES from user input and returns
  them so main.ts can log a warning
- move JAVA_HOME to exact names, use JAVA_HOME_ as prefix for clarity
- update stale suffix-based description in waitlist email script

Made-with: Cursor

* fix wiki/security.md snippet: JAVA_HOME -> JAVA_HOME_ to match code

Made-with: Cursor

* UI polish: field-sizing-content on all textareas, rename env allowlist label

- add field-sizing-content to all settings textareas so they auto-expand
  to fit content (AgentSettings, ModesSettings, WorkflowsSettings, FlagsSettings)
- rename "Environment variable passthrough" to "Environment allowlist"
  with clearer popover copy
- drop "e.g." prefix from env allowlist placeholder
- update docs/security.mdx and wiki/security.md references to match

Colin McDonnell c86752cf1d require OIDC verification for DB secrets on run-context (#538)
* add wiki/betterstack.md documenting log querying, request-ID grouping, and MCP usage

Made-with: Cursor

* fix webhook race conditions: separate runId assignment from data updates

the workflow_run webhook handler had a race where concurrent handlers assigned
the same runId to different pending records. the loser's P2002 silently dropped
data updates (jobId, status, completedAt). fix by splitting into two steps:
assignRunId() handles the race-safe unique assignment, then data updates always
target where: { runId } so they hit the correct record regardless of who won.

also downgrade R2 ObjectLockedByBucketPolicy errors from error to warn level
since duplicate webhook deliveries writing the same key is expected under load.

Made-with: Cursor

* require OIDC verification for DB secrets on run-context endpoint

DB secrets transported via run-context were accessible to any GitHub API
token with read access, bypassing GitHub Actions' fork PR secret isolation.
Now the endpoint requires a valid GitHub Actions OIDC token
(X-GitHub-OIDC-Token header) with a matching repository claim before
returning dbSecrets. Also requires admin for account-scope CLI secret
writes (matching the dashboard), and removes dead redactSecrets code.

Colin McDonnell 6f108237d4 Deployment protection bypass (#298)
* test preview bypass 2

Co-authored-by: Cursor <cursoragent@cursor.com>

* add apiFetch wrapper with Vercel bypass via query param + header

the template workflow was missing VERCEL_AUTOMATION_BYPASS_SECRET,
so all action API calls to preview deployments hit Vercel's
deployment protection without bypass. this also consolidates the
bypass logic into a single fetch wrapper that applies the secret
as both a query parameter (matching server-side forwarding) and
a header for belt-and-suspenders reliability.

Co-authored-by: Cursor <cursoragent@cursor.com>

* security hardening for Vercel bypass

- redact bypass token from webhook forwarder logs and response body
- remove dead x-preview-api-forward header
- refactor getAllSecrets() to use SENSITIVE_PATTERNS instead of hardcoded list
- enforce https:// on API_URL (localhost exempt for local dev)

Colin McDonnell 3a7145db1a Scope installation token permissions in restricted mode (#226)
* Scope installation token permissions in restricted mode

In restricted/disabled bash mode, the installation token is now scoped
to match the workflow's permissions block. This preserves fork push
capability while limiting what the agent can do with the token.

- Read workflow permissions from pullfrog.yml at runtime
- Pass permissions to API when acquiring installation token
- Clear OIDC env vars in restricted mode to prevent token minting
- Simplify setupGit by moving token resolution to main.ts

* Address review feedback: fail closed with default permissions

- Add restrictive default permissions (contents:read, pull_requests:read,
  issues:read) as fallback when workflow permissions can't be read
- Add support for job-level permissions via GITHUB_JOB env var
- Fix misleading comment about token resolution in restricted mode
- Add documentation about fork PR checkout behavior

* Simplify to separate git/MCP tokens without workflow permission scoping

- gitToken: minimal contents:write only (assumed exfiltratable)
- mcpToken: full installation token (not exfiltratable via MCP tools)
- Remove workflowPermissions.ts - security-conscious users can pass
  their own token via GH_TOKEN or inputs.token
- Add type-safe InstallationTokenPermissions to github.ts and API route

* Rename `write` permission to `push` and remove vestigial tool blocking

The `write` permission was previously used to block local file write tools
in agents. This was security theater since bash can write files anyway.

Now `push` only controls the git token scope:
- push: enabled → contents:write (can push commits)
- push: disabled → contents:read (read-only, can't push)

Changes:
- Rename `write` to `push` in action.yml, Prisma schema, and all TS types
- Remove vestigial write tool blocking from all agents (claude, cursor,
  gemini, opencode, codex)
- Add data-preserving Prisma migration using RENAME COLUMN
- Update UI: "Write files" → "Git push" with updated description

* add PID namespace isolation for bash sandbox

when running in CI, attempts to use unshare --pid to create a new PID
namespace for bash subprocesses. this prevents the /proc/$PPID/environ
attack where a malicious command could read secrets from the parent
process's environment.

the protection works by:
1. creating a new PID namespace (subprocess becomes PID 1)
2. mounting fresh /proc showing only sandbox PIDs
3. parent PIDs become invisible (PPID = 0, /proc/0 doesn't exist)

combined with filterEnv(), this provides complete protection against
/proc-based secret theft. falls back gracefully if namespaces aren't
available.

includes test script to verify the protection works.

* add PID namespace test to CI workflow

tests whether unshare --pid works on GHA runners out of the box,
and if not, whether enabling via sysctl helps. also runs the
pidNamespace.ts test to verify the full protection.

* fix pnpm setup and add procIsolation agent test

- fix pnpm/action-setup by specifying package_json_file path
- add procIsolation crossagent test that has agent attempt to
  read secrets via /proc/$PPID/environ
- add procIsolation to CI test matrix

* add pid-namespace test job to main workflow

this job tests unshare --pid capabilities on GHA runners and runs
the pidNamespace.ts adhoc test to verify /proc isolation works

* test bubblewrap's sysctl approach for enabling namespaces

- write to /etc/sysctl.d/99-userns.conf and run sysctl --system
- try aa-complain on unshare binary
- more detailed diagnostics

* fix pidNamespace test and add sudo-unshare fallback for GHA

- fix reference error in pidNamespace.ts (renamed function but didn't update calls)
- add sudo-unshare as fallback method for GHA runners where unprivileged
  namespaces are blocked but sudo is available
- update bash.ts to detect and use sudo unshare when unprivileged fails

* consolidate security docs and document PID namespace isolation

- update security.md with current implementation details
  - document sudo unshare fallback for GHA runners
  - add testing instructions for local Docker and CI
  - add "Further Exploration" section with Landlock and path validation ideas
- delete bash-sandbox.md and landlock.md (consolidated into security.md)

* move procIsolation test to adhoc folder

the procIsolation test requires PID namespace capabilities that aren't
available in the Docker test environment. moved to adhoc/ so it's excluded
from default test runs and can be run explicitly when needed (e.g. via
the pid-namespace CI job or locally with --privileged docker).

* fix Docker test environment for PID namespace isolation

- add CI and GITHUB_ACTIONS to testEnvAllowList so sandbox detection runs
- add --privileged to Docker run for PID namespace support (unshare)

this fixes the test environment to properly test the sandbox. in production,
the action runs directly on GHA runner where sudo unshare works.

* fix getJobToken() to work in test environment

add fallback to GH_TOKEN and GITHUB_TOKEN when INPUT_TOKEN is not set.
this allows tests to run without requiring workflow-level token input.

the token resolution order is:
1. INPUT_TOKEN (from workflow `with: token:`)
2. GH_TOKEN (external token override)
3. GITHUB_TOKEN (pre-acquired in tests or from GHA env)

* security: filter secrets from all subprocess environments

- extract filterEnv() to shared utils/secrets.ts
- make $() utility filter secrets by default (git, npm, etc. don't need them)
- disable git hooks via core.hooksPath to prevent hook-based exfiltration
- git auth uses token embedded in URL, not env vars

this prevents malicious git hooks, npm postinstall scripts, and other
code execution vectors from exfiltrating GITHUB_TOKEN and API keys.

* docs: clarify defense-in-depth security model

update security.md to explain why BOTH layers are required:
- filterEnv(): cleans child's own /proc/self/environ
- PID namespace: hides parent's /proc entries

PID namespace alone isn't sufficient - with --mount-proc, the child
becomes PID 1, so /proc/1/environ is the child's OWN environment.
without filterEnv(), secrets would still be accessible there.

* add procSandbox crossagent test for PID namespace security

- add crossagent/procSandbox.ts: security test that instructs agent to try
  various /proc attack vectors and validates sandbox blocks them
- update wiki/security.md: document PID namespace isolation details, add
  verification commands, explain why sudo inside sandbox doesn't break security
- update docker.ts: use node:24 with sudo for GHA-like test environment
- update instructions.ts: allow disabling security messaging for pentests
- clean up adhoc test files (procIsolation.ts, securityAudit.ts)

the procSandbox test sets SANDBOX_TEST_TOKEN (matches *_TOKEN filter), gives
the agent explicit hints about attack vectors (/proc, sudo, nsenter, etc.),
disables prompt-based mitigations, and validates the secret is never leaked.

* move procSandbox test to agnostic/ (runs with one agent)

* WIP

* docs: add agent testing guide (pnpm play, Docker, pentesting)

* docs: add CI details to agent testing guide

* docs: add interesting findings and gotchas from pentesting

* improve test fidelity: auto-set CI=true, verify sandbox active

- docker.ts: always set CI=true in container so sandbox activates
- docker.ts: skip sudo/user setup if already done (faster reruns)
- bash.ts: export getSandboxMethod() for diagnostics
- bash.ts: add debug log when sandbox disabled
- procSandbox.ts: add sandbox_was_active check to catch vacuous passes

the CI=true change is critical: without it, PID namespace isolation
is skipped and security tests pass without actually testing anything.

* docs: update agent-testing.md with CI=true auto-set note

* docs: clarify log format is agent-specific

* fix git auth, simplify MCP tools, add adversarial tests

- fix gitWithAuth to use Basic auth format (Bearer doesn't work with git's http.extraheader)
- fix token.ts: push:restricted now correctly gets contents:write
- fix github.ts: pass permissions when acquiring installation tokens locally
- remove commit_files and create_branch MCP tools (redundant, don't require credentials)
- remove containsSecrets() - trivially bypassable, not sound security
- add agnostic adversarial tests: pushDisabled, pushRestricted, tokenExfil
- update instructions.ts to clearly list available git MCP tools
- add wiki/git.md documenting credential isolation and push permission tiers
- update wiki/docker.md with custom image considerations
- update wiki/agent-testing.md with adversarial testing patterns

* fix type errors after rebase

- change ResolveTokensParams.push from ToolPermission to PushPermission
- use tags: ["agnostic"] instead of agnostic: true in test files

* fix cleanup permission error in sandbox tests

when sandbox isolation is enabled (CI=true), files created by the unshare
subprocess may have different ownership, causing rmSync to fail with EACCES.
this error in the finally block was overriding the test's success result.

fix: wrap cleanup in try-catch and fall back to sudo rm if rmSync fails.

* Add adhoc

* Handle git config/remote bypasses

* add git hooks protection and simplify ToolState

- disable git hooks in restricted mode via -c core.hooksPath=/dev/null
- add gitHooks adversarial test to verify hook protection works
- unify prNumber/issueNumber into single issueNumber field
- add pushUrl to ToolState for push validation
- add generateTestMarker() for simpler single-agent test markers
- export SENSITIVE_PATTERNS and isSensitiveEnvName from secrets.ts
- remove redundant pidNamespace.ts (duplicated by procSandbox.ts)
- update documentation

* harden $git() auth: subcommand whitelist, binary tamper detection

- rename gitWithAuth() to $git() with explicit subcommand first arg
- restrict to "fetch" | "push" at type level (filters don't run for these)
- resolve git binary path at startup via resolveGit(), sha256 fingerprint
- verify hash before each $git() call to detect binary replacement
- rename disableHooks to restricted for cleaner semantics
- document filter exfiltration attack and empirical verification in wiki

* remove redundant pid-namespace CI job

the PID namespace isolation testing is now handled by
action/test/agnostic/procSandbox.ts via pnpm runtest agnostic

* fix push_branch for new branches and improve token leak detection

- getPushDestination now falls back to origin/<branch> when @{push}
  is not configured (happens for new branches created locally)
- gitPerms validator now checks for actual token patterns instead
  of matching "x-access-token" string in test instructions

* use kebab-case for test names

* simplify shell env API: "restricted" | "inherit" | object

replace passFullEnv boolean with cleaner env option that accepts:
- "restricted" (default): filterEnv() to prevent secret leakage
- "inherit": full process.env
- object: custom env merged with restricted base

* share EnvMode and resolveEnv between shell.ts and bash.ts

move shared env resolution logic to secrets.ts

* add env option to bash tool (default: restricted)

* delete agent-testing.md (renamed to adversarial.md)

* Add checkout tests

* reframe githooks test prompt to avoid claude safety refusal

claude was refusing to execute the test because the prompt used words
like "malicious" and "security testing". reframed as a debugging task
with innocuous env var name (TESTING_DEBUG_TAG) per adversarial.md guidance.

* clean up verbose token acquisition logs

move logging responsibility to call sites which have better context
(git token vs MCP token). remove redundant intermediate OIDC logs
and unused "(permission-scoped)" suffix.

* isolate agnostic tests with matrix strategy, fix .pullfrog-env secret leak

- split action-agnostic into per-test matrix jobs for isolated logs and filesystems
- only write explicitly opted-in env vars to .pullfrog-env via fileAgentEnv
  (fixes token-exfil test where claude found SANDBOX_TEST_TOKEN on disk)
- mcpmerge test opts in via fileAgentEnv for cursor's repo-level MCP fallback

Co-authored-by: Cursor <cursoragent@cursor.com>

* remove env parameter from bash tool to prevent agents bypassing filterEnv

the bash tool exposed an `env` parameter accepting "restricted" | "inherit"
which allowed agents to pass env: "inherit" and see all secrets including
SANDBOX_TEST_TOKEN, bypassing the restricted environment filtering entirely.
env mode is now determined internally (always restricted).

* use pullfrog/test-repo for push tests to stop polluting main repo

push tests were creating branches and tags on pullfrog/app directly.
now all push tests (push-restricted, push-disabled, push-enabled,
git-permissions) target pullfrog/test-repo instead.

Co-authored-by: Cursor <cursoragent@cursor.com>

* use pullfrog/test-repo for all tests, not just push tests

no test should clone or operate on pullfrog/app directly.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix token scoping for test-repo and bash timeout defaults

- acquireTokenViaOIDC now includes GITHUB_REPOSITORY repo in token
  scope so push tests work against pullfrog/test-repo
- bash tool default timeout: 120s -> 30s, cap: 600s -> 120s
- activity timeout: 30s -> 60s
- prevents hung bash commands (e.g. find /) from killing the agent
  via activity timeout
