CVE-2026-73658
HighCVSS 8.2Exploitation Probability (EPSS)
Low risk26th percentile - higher than 26% of all known CVEs
Summary
Trigger.dev from version 4.4.2 to 4.5.0-rc.5 has a vulnerability in Aws4FetchClient.buildUrl() and presign() where user-controlled packet keys are assigned to URL.pathname, and the route accepts params without rejecting dot segments and without per-resource ownership validation. WHATWG path normalization collapses .. segments before signing, allowing a caller with a valid environment API key to obtain presigned URLs for another tenant's object-store keys and read or overwrite task payloads.
Risk Assessment
Risk of unauthorized access to other tenants' data, potentially leading to data leakage or manipulation of task payloads.
Recommendation
Update Trigger.dev to version 4.5.0-rc.5 or later, which includes the fix.
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.5, Aws4FetchClient.buildUrl() and Aws4FetchClient.presign() in apps/webapp/app/v3/objectStoreClient.server.ts assign user-controlled packet keys to URL.pathname, while apps/webapp/app/routes/api.v1.packets.$.ts accepts params["*"] without rejecting dot segments and uses findResource: async () => 1 without per-resource ownership validation. WHATWG path normalization collapses .. segments before signing, allowing a caller with a valid environment API key to obtain presigned URLs for another tenant's object-store keys and read or overwrite task payloads. This issue is fixed in version 4.5.0-rc.5.
