CVE-2026-114077 triggerdotdev CVE debrief

Who should care

Trigger.dev users and administrators should verify their deployment configurations and update to version 4.5.6 or later to prevent potential deployment hijacking. Affected users include those with Trigger.dev deployments, security teams, and platform administrators responsible for managing and securing Trigger.dev environments. Users should review and validate their deployment configurations to prevent potential unauthorized modifications.

Why it matters

Trigger.dev users should verify deployment configurations and update to version 4.5.6 or later to prevent potential deployment hijacking

• Deployment hijacking via createDeploymentBackgroundWorkerV4
• Potential for unauthorized deployment modifications
• Need for verification of deployment configurations

Technical summary

Trigger.dev before 4.5.6 contains an authorization bypass vulnerability in createDeploymentBackgroundWorkerV4, allowing attackers holding only their own environment API key to POST to the deployment background-workers endpoint with a victim's deployment ID. This enables re-pointing that in-progress deployment at a worker in the attacker's environment, posing a medium severity risk with a CVSS score of 6.1. The vulnerability is confirmed in createDeploymentBackgroundWorkerV4, and users should review and validate their deployment configurations to prevent potential unauthorized modifications.

Defensive priority

Trigger.dev users should verify their deployment configurations

Recommended defensive actions

• Verify Trigger.dev deployment configurations for potential hijacking
• Update Trigger.dev to version 4.5.6 or later
• Monitor deployment background workers for suspicious activity
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
