Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-2181 exists.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected all versions; fixed in 15.9.8, 15.10.7, 15.11.3\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-2023-2181/ (Markdown: https://insights.sbomify.com/CVE-2023-2181/index.md)","id":"CVE-2023-2181","markdown":"https://insights.sbomify.com/CVE-2023-2181/index.md","name":"CVE-2023-2181","record":{"aliases":["BIT-gitlab-2023-2181","GHSA-m96m-mfqc-86mf","UBUNTU-CVE-2023-2181"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"GitLab","requires_auth":"low_privilege","summary":"A malicious developer can smuggle hidden content into merge requests using git refs/replace, bypassing code review visibility in GitLab.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[{"product":"gitlab","vendor":"gitlab"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[],"description":"An issue has been discovered in GitLab affecting all versions before 15.9.8, 15.10.0 before 15.10.7, and 15.11.0 before 15.11.3.
