Description

Dulwich from 0.24.0 before 1.2.8 contains a symlink following vulnerability in porcelain.checkout(paths=[...]) that allows attackers to write arbitrary files by abusing raw os.open without O_NOFOLLOW. Attackers can craft a repository where a worktree symlink points to .git/hooks/post-checkout, so restoring the file from a tag writes a malicious hook for code execution.

Trigger.dev before 4.7.0 contains a missing authorization vulnerability that allows holders of unrestricted environment API keys to block runs they do not own by supplying a foreign parentRunId to batch-creation endpoints. Attackers can send requests to POST /api/v3/batches or POST /api/v2/tasks/batch with resumeParentOnCompletion to suspend, indefinitely block, or inject errors into production or cross-organization runs.

CVE-2026-114068

Trigger.dev before 4.6.0 contains a missing authorization vulnerability in the waitpoint token wait endpoint that allows authenticated attackers to block runs belonging to other organizations. Attackers holding any secret API key can supply a victim run ID with their own waitpoint, causing that run to block indefinitely on a waitpoint the victim cannot complete, and can inject resume data into it.

CVE-2026-114069

Trigger.dev before 4.6.0 contains an improper authorization vulnerability in the GET /api/v1/projects/:projectRef/envvars endpoint, which returns the environment's root API key as TRIGGER_SECRET_KEY for staging, production, and preview environments. Attackers holding a restricted read:envvars key can obtain the root secret and plaintext secrets, then trigger tasks and mint admin public JWTs.
