CISA Known Exploited Vulnerabilities (KEV) Catalog

EPSS Score97.4%

EPSS (Exploit Prediction Scoring System) estimates a 97.4% chance this CVE is exploited in the wild within the next 30 days — higher than 100% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

GitLab Community Edition and Enterprise Edition contains a path traversal vulnerability that allows an unauthenticated user to read arbitrary files due to an improper path confinement and missing authentication enforcement in the repository commits API.

Required Action
Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
