CVE-2026-85650 — Trigger.dev before 4.5.2 Server-Side Request Forgery via webhook alert-channel

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.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • Technical severity (medium)+3
  • CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Triggerdotdev Trigger.dev).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (ssrf), errors and authentication anomalies.
