An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-3424 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected from 10.3.0; fixed in 15.11.10, 16.0.6, 16.1.1\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-2023-3424/ (Markdown: https://insights.sbomify.com/CVE-2023-3424/index.md)","id":"CVE-2023-3424","markdown":"https://insights.sbomify.com/CVE-2023-3424/index.md","name":"CVE-2023-3424","record":{"aliases":["BIT-gitlab-2023-3424","GHSA-73w2-5f6g-jx42","UBUNTU-CVE-2023-3424"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GitLab","requires_auth":"none","summary":"Attackers can cause a denial of service in GitLab by sending crafted payloads to the preview_markdown endpoint, triggering inefficient regular expression processing.","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":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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 CE/EE affecting all versions starting from 10.3 before 15.11.10, all versions starting from 16.0 before 16.0.6, all versions starting from 16.1 before 16.1.1.
