Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-3979 exists.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected from 10.6.0; fixed in 16.2.8, 16.3.5, 16.4.1\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-2023-3979/ (Markdown: https://insights.sbomify.com/CVE-2023-3979/index.md)","id":"CVE-2023-3979","markdown":"https://insights.sbomify.com/CVE-2023-3979/index.md","name":"CVE-2023-3979","record":{"aliases":["BIT-gitlab-2023-3979","GHSA-ppjq-2qhc-pjp7","UBUNTU-CVE-2023-3979"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"GitLab","requires_auth":"low_privilege","summary":"Upstream collaborators can improperly write to merge request source branches, allowing unauthorized code modification in GitLab.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[{"product":"gitlab","vendor":"gitlab"}],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"An issue has been discovered in GitLab affecting all versions starting from 10.6 before 16.2.8, all versions starting from 16.3 before 16.3.5, all versions starting from 16.4 before 16.4.1.
