CVE-2026-97229: Integer Overflow or Wraparound in GitLab

Noroxi assessment

Priority: This week (action score 78/100)

  • CISA has confirmed exploitation in the wild (Oct 29, 2026). Remediation deadline for US federal agencies: Nov 1, 2026.
  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 27.3% (FIRST EPSS); higher than 98% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: GitLab GitLab 19.2.8, 19.3.5, 19.4.2; azl3 ruby 3.3.5-10 on Azure Linux 3.0 3.3.13-0; azl4 ruby 3.4.10-36.azl4 on Azure Linux 4.0 0:3.4.12-38.azl4.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Upgrade to GitLab GitLab 19.2.8, 19.3.5, 19.4.2; azl3 ruby 3.3.5-10 on Azure Linux 3.0 3.3.13-0; azl4 ruby 3.4.10-36.azl4 on Azure Linux 4.0 0:3.4.12-38.azl4 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 · CISA KEV · FIRST EPSS

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 19.2 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed 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.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Oct 29, 2026. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Nov 1, 2026.
