Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-39881 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected from 7.7.0; fixed in 14.1.7, 14.2.5, 14.3.1\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-2021-39881/ (Markdown: https://insights.sbomify.com/CVE-2021-39881/index.md)","id":"CVE-2021-39881","markdown":"https://insights.sbomify.com/CVE-2021-39881/index.md","name":"CVE-2021-39881","record":{"aliases":["BIT-gitlab-2021-39881","GHSA-4ff8-x6j5-88r4","UBUNTU-CVE-2021-39881"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"GitLab","requires_auth":"low_privilege","summary":"Attackers can create OAuth clients with spoofed scopes to trick users into granting unauthorized access, requiring GitLab administrators to apply patches.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[{"product":"gitlab","vendor":"gitlab"}],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[],"description":"In all versions of GitLab CE/EE since version 7.7, the application may let a malicious user create an OAuth client application with arbitrary scope names which may allow the malicious user to trick unsuspecting users to authorize the malicious client application using the spoofed scope name and description.","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":"Security feature bypass in GitLab","id":"CVE-2021-39881","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"gitlab:gitlab","products":["gitlab:gitlab"],"type":"security_feature_bypass","year":"2021"},"n_packages":1,"n_references":3,"next":{"headline":"Information disclosure in GitLab","id":"CVE-2021-39882"},"packages":[{"ecosystem":"Bitnami","fixed":["14.1.7","14.2.5","14.3.1"],"introduced":["7.7.0","14.2.0","14.3.0"],"last_affected":[],"package":"gitlab","purl":"pkg:bitnami/gitlab","source":"BIT-gitlab-2021-39881"}],"prev":{"headline":"apollo_upload_server has Denial of Service vulnerability","id":"CVE-2021-39880"},"products":["GitLab"],"published":"2021-10-05","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["GitLab"]},"summary":"Attackers can create OAuth clients with spoofed scopes to trick users into granting unauthorized access, requiring GitLab administrators to apply patches.","url":"https://insights.sbomify.com/CVE-2021-39881/"}
