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-2020-13334 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected from 8.6.0; fixed in 13.2.10, 13.3.7, 13.4.2\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-2020-13334/ (Markdown: https://insights.sbomify.com/CVE-2020-13334/index.md)","id":"CVE-2020-13334","markdown":"https://insights.sbomify.com/CVE-2020-13334/index.md","name":"CVE-2020-13334","record":{"aliases":["BIT-gitlab-2020-13334","GHSA-2px3-3vqh-4m6q","UBUNTU-CVE-2020-13334"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"GitLab","requires_auth":"none","summary":"Non-members can modify issue confidentiality via GraphQL due to improper authorization checks 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":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"In GitLab versions prior to 13.2.10, 13.3.7 and 13.4.2, improper authorization checks allow a non-member of a project/group to change the confidentiality attribute of issue via mutation GraphQL query","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Missing authorization in GitLab","id":"CVE-2020-13334","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":"Business logic in GitLab","id":"CVE-2020-13335"},"packages":[{"ecosystem":"Bitnami","fixed":["13.2.10","13.3.7","13.4.2"],"introduced":["8.6.0","13.3.0","13.4.0"],"last_affected":[],"package":"gitlab","purl":"pkg:bitnami/gitlab","source":"BIT-gitlab-2020-13334"}],"prev":{"headline":"Denial of service in GitLab","id":"CVE-2020-13333"},"products":["GitLab"],"published":"2020-10-07","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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["GitLab"]},"summary":"Non-members can modify issue confidentiality via GraphQL due to improper authorization checks in GitLab.","url":"https://insights.sbomify.com/CVE-2020-13334/"}
