Plain-English Summary

CVE-2026-97229 is a confirmed actively exploited vulnerability affecting GitLab Community Edition and Enterprise Edition. Tracked in the CISA Known Exploited Vulnerabilities (KEV) catalog as GitLab Community Edition and Enterprise Edition Integer Overflow or Wraparound Vulnerability, this flaw carries a CVSS base score of 8.8 (HIGH) and an EPSS exploitation probability of 69.29%. Because real-world threat actors are actively abusing this weakness in production environments, defenders and system administrators must treat patching or network-level isolation as an immediate priority rather than waiting for routine maintenance cycles.

According to defensive advisory data, GitLab Community Edition and Enterprise Edition contain a integer overflow or wraparound vulnerability that could allow an unauthenticated user to execute arbitrary code on the GitLab server via a specially crafted regular expression in a CI/CD configuration, due to insufficient regular expression validation. Organizations running exposed or unpatched instances of GitLab Community Edition and Enterprise Edition face heightened operational risk, including unauthorized access, service disruption, or lateral movement depending on deployment architecture. Ransomware campaign association is currently recorded as 'Unknown'. If your environment exposes Community Edition and Enterprise Edition to untrusted networks, remote users, or partner integrations, prioritize verification of your current software build today.
