Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-39927 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected from 8.4.0; fixed in 14.4.5, 14.5.3, 14.6.2\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-2021-39927/ (Markdown: https://insights.sbomify.com/CVE-2021-39927/index.md)","id":"CVE-2021-39927","markdown":"https://insights.sbomify.com/CVE-2021-39927/index.md","name":"CVE-2021-39927","record":{"aliases":["BIT-gitlab-2021-39927","GHSA-76g9-63cr-m776","UBUNTU-CVE-2021-39927"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"GitLab","requires_auth":"low_privilege","summary":"Attackers can bypass SSRF protections to access localhost services when GitLab runs on non-standard ports, potentially exposing internal data.","user_interaction":"not_required","vuln_class":"ssrf"},"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:H/PR:L/UI:N/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Server side request forgery protections in GitLab CE/EE versions between 8.4 and 14.4.4, between 14.5.0 and 14.5.2, and between 14.6.0 and 14.6.1 would fail to protect against attacks sending requests to localhost on port 80 or 443 if GitLab was configured to run on a port other than 80 or 443","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":"Server-side request forgery in GitLab","id":"CVE-2021-39927","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"gitlab:gitlab","products":["gitlab:gitlab"],"type":"ssrf","year":"2021"},"n_packages":1,"n_references":2,"next":{"headline":"NULL pointer exception in the IEEE 802.11 dissector in Wireshark 3.4.0 to 3.4.9 and 3.2.0 to 3.2.17 allows denial of service via packet inje","id":"CVE-2021-39928"},"packages":[{"ecosystem":"Bitnami","fixed":["14.4.5","14.5.3","14.6.2"],"introduced":["8.4.0","14.5.0","14.6.0"],"last_affected":[],"package":"gitlab","purl":"pkg:bitnami/gitlab","source":"BIT-gitlab-2021-39927"}],"prev":{"headline":"Memory corruption in Wireshark","id":"CVE-2021-39926"},"products":["GitLab"],"published":"2022-01-18","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":"Attackers can bypass SSRF protections to access localhost services when GitLab runs on non-standard ports, potentially exposing internal data.","url":"https://insights.sbomify.com/CVE-2021-39927/"}
