Trigger.dev: Run replay injects a task run into an attacker-chosen environment (cross-tenant write)

CVE-2026-85651GHSA-qxpp-qjg8-x4jv

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (trigger.dev 4.5.2), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Summary The dashboard replay action authorizes the source run (it must belong to the caller's org), but the target environment for the replayed run is taken verbatim from the request body and is never checked for org or project membership. The environment lookup used by the replay path filters by id only. As a result, an authenticated user can replay one of their own runs into another organization's or project's environment, creating a task run there that consumes the victim tenant's queue and compute and pollutes their run history. Details The replay action member-scopes the source run correctly (apps/webapp/app/routes/resources.taskruns.$runParam.replay.ts, the findFirst on taskRun filtered by project.organization.members.some.userId), but passes the target environment straight from the submitted form, resources.taskruns.$runParam.replay.ts:344-346: submission.value.environment comes from ReplayRunData (apps/webapp/app/v3/replayTask.ts: environment: z.string().optional()), so it is…

# Patch Next advisory brief: CVE-2026-85651

Advisory: Trigger.dev: Run replay injects a task run into an attacker-chosen environment (cross-tenant write)
IDs: CVE-2026-85651, GHSA-qxpp-qjg8-x4jv
Record: https://patchnext.com/advisories/ghsa-qxpp-qjg8-x4jv (revision 3, source checked 26 Oct 2026, 13:06 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: trigger.dev 4.5.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm trigger.dev: affected < 4.5.2; fixed in 4.5.2

## Suggested inspection (read-only)
- `npm ls trigger.dev --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on trigger.dev.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-qxpp-qjg8-x4jv (GitHub-reviewed advisory GHSA-qxpp-qjg8-x4jv lists affected ranges: npm trigger.dev >=0 <4.5.2)
- Verified: https://osv.dev/vulnerability/GHSA-qxpp-qjg8-x4jv (OSV record GHSA-qxpp-qjg8-x4jv lists affected ranges: npm trigger.dev >=0 <4.5.2 (fixed))
