{"id":"CVE-2026-73659","aliases":["GHSA-m3mf-37q7-8928"],"url":"https://o3.security/vulnerability/CVE-2026-73659","summary":"Trigger.dev: Cross-tenant object read/write via path traversal in packet presign API","details":"Trigger.dev is the open-source platform for building AI workflows in TypeScript. From 4.4.2 until 4.5.0, the packet presign routes in apps/webapp/app/routes/api.v1.packets.$.ts pass a caller-controlled filename through resolveStoreProtocolForPacketPresign to generatePresignedUrl and generatePresignedRequest in apps/webapp/app/v3/objectStore.server.ts, allowing .. traversal to escape the packets/<projectRef>/<env>/ object-store prefix and enabling a project API key to read or overwrite another organization's offloaded task payloads and outputs on multi-organization self-hosted instances. This issue is fixed in version 4.5.0.","published":"2026-08-13T21:19:48.451Z","modified":"2026-08-15T04:07:06.073940036Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/triggerdotdev/trigger.dev/commit/db4074df54db06b0656becf3f974345c90fa202e","label":"triggerdotdev/trigger.dev@db4074d"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73659.json"},{"type":"FIX","url":"https://github.com/triggerdotdev/trigger.dev/commit/db4074df54db06b0656becf3f974345c90fa202e"},{"type":"FIX","url":"https://github.com/triggerdotdev/trigger.dev/pull/3830"},{"type":"WEB","url":"https://github.com/triggerdotdev/trigger.dev/releases/tag/v4.5.0"},{"type":"ADVISORY","url":"https://github.com/triggerdotdev/trigger.dev/security/advisories/GHSA-m3mf-37q7-8928"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73659"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-15T04:07:06.073940036Z"}}
