An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-13308 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected from 1.0.0; fixed in 13.1.10, 13.2.8, 13.3.4\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-2020-13308/ (Markdown: https://insights.sbomify.com/CVE-2020-13308/index.md)","id":"CVE-2020-13308","markdown":"https://insights.sbomify.com/CVE-2020-13308/index.md","name":"CVE-2020-13308","record":{"aliases":["BIT-gitlab-2020-13308","GHSA-6fvc-pc2f-vcp7","UBUNTU-CVE-2020-13308"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"GitLab","requires_auth":"high_privilege","summary":"Attackers can deny service to users without 2FA by inviting them to projects enforcing 2FA inheritance, locking them out of GitLab.","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":2.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-281","name":"Improper Preservation of Permissions"}],"description":"A vulnerability was discovered in GitLab versions before 13.1.10, 13.2.8 and 13.3.4.
