Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-13277 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected from 10.6.0; fixed in 12.9.10, 12.10.11, 13.0.6\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-2020-13277/ (Markdown: https://insights.sbomify.com/CVE-2020-13277/index.md)","id":"CVE-2020-13277","markdown":"https://insights.sbomify.com/CVE-2020-13277/index.md","name":"CVE-2020-13277","record":{"aliases":["BIT-gitlab-2020-13277","GHSA-23r2-7xm3-g75g"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"GitLab","requires_auth":"low_privilege","summary":"Attackers can read private repositories due to an authorization flaw in GitLab's mirroring logic.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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:H/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"An authorization issue in the mirroring logic allowed read access to private repositories in GitLab CE/EE 10.6 and later through 13.0.5","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":"2020-10-31","github_poc":1,"max_poc_stars":28,"metasploit":0,"nuclei":0,"refs":[{"date":"2020-10-31T11:01:26Z","kind":"github_poc","ref":"https://github.com/EXP-Docs/CVE-2020-13277","stars":28,"title":"CVE-2020-13277 靶场： Gitlab 逻辑漏洞 - 任意用户越权访问私有仓库"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Missing authorization in GitLab","id":"CVE-2020-13277","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"gitlab:gitlab","products":["gitlab:gitlab"],"type":"missing_authorization","year":"2020"},"n_packages":1,"n_references":3,"next":{"headline":"Reflected cross-site scripting in francoisjacquet/rosariosis","id":"CVE-2020-13278"},"packages":[{"ecosystem":"Bitnami","fixed":["12.9.10","12.10.11","13.0.6"],"introduced":["10.6.0","12.10.0","13.0.0"],"last_affected":[],"package":"gitlab","purl":"pkg:bitnami/gitlab","source":"BIT-gitlab-2020-13277"}],"prev":{"headline":"Missing authorization in GitLab","id":"CVE-2020-13276"},"products":["GitLab"],"published":"2020-06-19","related":[{"cvss_score":10,"headline":"GitLab Community Edition and Enterprise Edition Integer Overflow or Wraparound","id":"CVE-2026-97229","kev_date_added":"2026-10-29","published":"2026-10-13"},{"cvss_score":10,"headline":"GitLab Community Edition and Enterprise Edition Path Traversal","id":"CVE-2026-85706","kev_date_added":"2026-09-11","published":"2026-09-12"},{"cvss_score":10,"headline":"GitLab Community and Enterprise Editions Improper Access Control","id":"CVE-2023-7028","kev_date_added":"2024-05-01","published":"2024-01-12"},{"cvss_score":10,"headline":"GitLab Community and Enterprise Editions Remote Code Execution","id":"CVE-2021-22205","kev_date_added":"2021-11-03","published":"2021-04-23"},{"cvss_score":6.8,"headline":"GitLab Community and Enterprise Editions Server-Side Request Forgery (SSRF)","id":"CVE-2021-39935","kev_date_added":"2026-02-03","published":"2021-12-13"},{"cvss_score":6.8,"headline":"GitLab Server-Side Request Forgery (SSRF)","id":"CVE-2021-22175","kev_date_added":"2026-02-18","published":"2021-06-11"},{"cvss_score":10,"headline":"Integer Overflow or Wraparound in GitLab","id":"CVE-2026-110264","kev_date_added":null,"published":"2026-10-22"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["GitLab"]},"summary":"Attackers can read private repositories due to an authorization flaw in GitLab's mirroring logic.","url":"https://insights.sbomify.com/CVE-2020-13277/"}
