Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-6736 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected from 11.3.0; fixed in 16.7.6, 16.8.3, 16.9.1\n\nTask:\n1. 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-2023-6736/ (Markdown: https://insights.sbomify.com/CVE-2023-6736/index.md)","id":"CVE-2023-6736","markdown":"https://insights.sbomify.com/CVE-2023-6736/index.md","name":"CVE-2023-6736","record":{"aliases":["BIT-gitlab-2023-6736","GHSA-4fr5-6ccq-75w2","UBUNTU-CVE-2023-6736"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GitLab","requires_auth":"low_privilege","summary":"An attacker can cause client-side denial of service in GitLab by submitting malicious content in the CODEOWNERS file.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[{"product":"gitlab","vendor":"gitlab"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"An issue has been discovered in GitLab EE affecting all versions starting from 11.3 before 16.7.6, all versions starting from 16.8 before 16.8.3, all versions starting from 16.9 before 16.9.1.
