{"apiVersion":"1.0","identifier":"CVE-2026-73656","description":"Trigger.dev is a platform for building and deploying fully managed AI agents and workflows. Prior to 4.5.6, POST /api/v1/deployments/:deploymentId/background-workers calls CreateDeploymentBackgroundWorkerServiceV4.call() in apps/webapp/app/v3/services/createDeploymentBackgroundWorkerV4.server.ts, where workerDeployment.findFirst() selects a deployment by friendlyId without an environmentId predicate. A caller with a valid API key for one project can submit another project-s deployment identifier, link an attacker-owned background worker to the victim deployment, and move the victim deployment from BUILDING to DEPLOYING. This issue is fixed in version 4.5.6.","publishedAt":"2026-08-13T20:17:30","lastModifiedAt":"2026-08-14T19:18:01","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73656","cvssScore":9.9,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:H","epssProbability":0.00342,"riskScore":1.02,"affectedProduct":"Trigger.dev","affectedVersions":"<4.5.6","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73656","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73656","en":"https://www.redsauce.net/en/cves/CVE-2026-73656","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73656","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73656","de":"https://www.redsauce.net/de/cves/CVE-2026-73656","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73656","el":"https://www.redsauce.net/el/cves/CVE-2026-73656"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73656"}}
