How to Fix GHSA-59h8-w5q6-mfmp

To remediate this vulnerability, upgrade all affected Trigger.dev dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

trigger.dev fixed: 4.5.5 
npm install trigger.dev@4.5.5
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls trigger.dev

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-59h8-w5q6-mfmp, inspect your project dependencies using npm:

npm ls trigger.dev

Analyze the terminal output to locate any version of Trigger.dev in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.5.5), your application is affected.

Note: The npm ls trigger.dev command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-306: Missing Authentication for Critical Function, where the product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. In Trigger.dev, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Summary The POST handler for `/realtime/v1/streams/:runId/:streamId` has no authentication. Any entity that knows or guesses a run friendlyId can inject arbitrary data into its realtime stream. ## Vulnerability Details **File:** `apps/webapp/app/routes/realtime.v1.streams.$runId.$streamId.ts` The `action` handler (line 17) has no auth wrapper. The code comment says: "Plain action for backwards compatibility with older clients that don't send auth headers." The run lookup at line 29 uses `where: { friendlyId: runId }` with NO environment scoping (`runtimeEnvironmentId` is not checked), so production runs are accessible. Run friendlyIds follow predictable patterns (e.g., `run_1234abcd`). ## Steps to Reproduce ```bash # No authentication required curl -X POST "http://localhost:8030/realtime/v1/streams/run_KNOWN_ID/stream_1" -H "Content-Type: application/json" -d '{"injected": "data"}' ``` ## Impact Unauthenticated data injection into any run realtime stream. Cross-environment access (no scoping).
