Low risk6th percentile - higher than 6% of all known CVEs
Summary
Trigger.dev from version 4.4.2 to 4.5.0-rc.4 has a vulnerability in the POST /api/v1/runs/:runParam/replay endpoint. The database query does not filter by runtimeEnvironmentId, allowing any valid environment API key to replay another tenant's run by friendlyId. Additionally, when payloadType "application/store" is used, payload bytes can be overwritten by an attacker, leading to unauthorized actions.
Risk Assessment
An attacker can consume victim resources, repeat side effects, and potentially execute malicious code in the context of the victim's task, potentially leading to confidentiality and integrity breaches.
Recommendation
Update Trigger.dev to version 4.5.0-rc.4 or later. Restrict access to the replay endpoint and enforce strict permission controls for API keys.
Original NVD description (English source)
Trigger.dev is a platform for building and deploying fully managed AI agents and workflows. From 4.4.2 until 4.5.0-rc.4, `POST /api/v1/runs/:runParam/replay` in apps/webapp/app/routes/api.v1.runs.$runParam.replay.ts uses `prisma.taskRun.findUnique({ where: { friendlyId: runParam } })` without a runtimeEnvironmentId filter, then ReplayTaskRunService in apps/webapp/app/v3/services/replayTaskRun.server.ts replays the selected run in the victim environment. Any valid environment API key can therefore replay another tenant's run by friendlyId, consuming victim resources and repeating side effects; when `payloadType: "application/store"` is used, overrideExistingPayloadPacket() calls conditionallyImportPacket() on existingTaskRun.payload without an integrity check, so payload bytes overwritten through a separate object-store path-traversal vulnerability become attacker-controlled input to the victim task. This issue is fixed in version 4.5.0-rc.4.
