  "details": "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 () =\u003e 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.",
