Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-110264/ (Markdown: https://insights.sbomify.com/CVE-2026-110264/index.md)","id":"CVE-2026-110264","markdown":"https://insights.sbomify.com/CVE-2026-110264/index.md","name":"CVE-2026-110264","record":{"aliases":["ALPINE-CVE-2026-110264","AZL-111071","BELL-CVE-2026-110264","BIT-gitlab-2026-110264","DEBIAN-CVE-2026-110264","GHSA-83vq-rvff-66gw"],"analysis":null,"analysis_generated_by":null,"assigner":"GitLab","cpe":[{"product":"gitlab","vendor":"gitlab"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"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.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":"2026-10-22","github_poc":12,"max_poc_stars":2,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-22T18:22:11Z","kind":"github_poc","ref":"https://github.com/al4n4n/CVE-2026-110264","stars":2,"title":"CVE-2026-110264: GitLab pre-auth RCE via Onigmo integer overflow in org-ruby.
