CVE-2026-114076: Trigger.dev before 4.5.2 Blind SSRF via Alert Channel Webhook URL

MediumCVSS 5.3 · v4.0—No exploit Fix available

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: 0.33% (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 blind server-side request forgery vulnerability that allows authenticated tenants to make the webapp server send POST requests to internal hosts by setting an unvalidated webhook alert channel URL. Attackers can point the webhook at internal services or cloud metadata addresses and trigger alerts to scan internal hosts, send state-changing POSTs, or reach IMDSv1 via redirects.
