CVE-2026-85650· NVD / CVE Program· CNA VulnCheck

Trigger.dev before 4.5.2 Server-Side Request Forgery via webhook alert-channel

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.34% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: triggerdotdev trigger.dev 4.5.2.

Low priority for now. Upgrade to triggerdotdev trigger.dev 4.5.2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Trigger.dev before 4.5.2 contains a server-side request forgery vulnerability in webhook alert channel delivery URLs that are fetched without validation or SSRF protection. Authenticated users with organization membership can create alert channels with URLs targeting internal services and metadata endpoints, allowing the server to issue POST requests to restricted resources.
