{"apiVersion":"1.0","identifier":"CVE-2026-73658","description":"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.","publishedAt":"2026-08-13T22:17:27","lastModifiedAt":"2026-08-14T17:20:35","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73658","cvssScore":8.2,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N","epssProbability":0.00332,"riskScore":0.84,"affectedProduct":"Trigger.dev","affectedVersions":">=4.4.2,<4.5.0-rc.5","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73658","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73658","en":"https://www.redsauce.net/en/cves/CVE-2026-73658","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73658","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73658","de":"https://www.redsauce.net/de/cves/CVE-2026-73658","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73658","el":"https://www.redsauce.net/el/cves/CVE-2026-73658"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73658"}}
