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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"triggerdotdev","product":"trigger.dev","versions":[{"version":">= 3.3.8, < 4.5.6","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:H","baseScore":8.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"HIGH"},"exploitabilityScore":3.1,"impactScore":4.7}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-08-14T16:33:32.438291Z","id":"CVE-2026-73654","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-1321"}]}],"references":[{"url":"https://github.com/triggerdotdev/trigger.dev/commit/6997aeb05e27d2db47f9eda01fdc8a17c81a1ae0","source":"security-advisories@github.com"},{"url":"https://github.com/triggerdotdev/trigger.dev/pull/4316","source":"security-advisories@github.com"},{"url":"https://github.com/triggerdotdev/trigger.dev/releases/tag/v4.5.6","source":"security-advisories@github.com"},{"url":"https://github.com/triggerdotdev/trigger.dev/security/advisories/GHSA-p28v-f755-9qrg","source":"security-advisories@github.com"},{"url":"https://github.com/triggerdotdev/trigger.dev/security/advisories/GHSA-p28v-f755-9qrg","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
