CVE-2026-110264: Integer Overflow or Wraparound in GitLab

Noroxi assessment

Priority: Plan (action score 40/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.3% (FIRST EPSS); higher than 71.4% 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 18.11.13, 19.0.10, 19.1.9; azl3 ruby 3.3.5-10 on Azure Linux 3.0 3.3.13-0.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Add it to your regular patch cycle. Upgrade to GitLab GitLab 18.11.13, 19.0.10, 19.1.9; azl3 ruby 3.3.5-10 on Azure Linux 3.0 3.3.13-0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An issue has been discovered in GitLab CE/EE affecting all versions from 7.0 before 18.11.13, 19.0 before 19.0.10, 19.1 before 19.1.9, 19.2 before 19.2.9, 19.3 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, under certain conditions, could have allowed an unauthenticated user to execute arbitrary code on the GitLab server due to integer overflow when compiling a specially crafted regular expression.
