From 3.3.8 until 4.5.6, the PUT /api/v1/runs/:runId/metadata endpoint passes attacker-controlled operation.key values to new JSONHeroPath(operation.key).set(newMetadata, value) in packages/core/src/v3/runMetadata/operations.ts without rejecting dangerous constructor and prototype path segments. A caller with a normal environment API key can pollute Object.prototype in the shared webapp process, corrupting Prisma queries and Prometheus labels, breaking other tenants' worker authentication, and causing a process-wide denial of service. This issue is fixed in version 4.5.6.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:H","score":8.5},"cwes":["CWE-1321"],"references":["https://github.com/triggerdotdev/trigger.dev/commit/6997aeb05e27d2db47f9eda01fdc8a17c81a1ae0","https://github.com/triggerdotdev/trigger.dev/pull/4316","https://github.com/triggerdotdev/trigger.dev/releases/tag/v4.5.6","https://github.com/triggerdotdev/trigger.dev/security/advisories/GHSA-p28v-f755-9qrg","https://github.com/triggerdotdev/trigger.dev/security/advisories/GHSA-p28v-f755-9qrg"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-73654","score":0.0062,"percentile":0.49725,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-p28v-f755-9qrg","url":"https://osv.dev/vulnerability/GHSA-p28v-f755-9qrg","summary":"Trigger.dev: Prototype pollution via run metadata operations → process-wide cross-tenant DoS","modified":"2026-08-13T21:11:02.927648Z","packages":[{"ecosystem":"npm","name":"@trigger.dev/core","purl":"pkg:npm/%40trigger.dev/core","ranges":[">=3.3.8 <4.5.6"],"fixed":["4.5.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
