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-2021-45330 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.6.0\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.6.0\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.6.0\n- gitea (Bitnami): affected all versions; fixed in 1.15.8\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-2021-45330/ (Markdown: https://insights.sbomify.com/CVE-2021-45330/index.md)","id":"CVE-2021-45330","markdown":"https://insights.sbomify.com/CVE-2021-45330/index.md","name":"CVE-2021-45330","record":{"aliases":["BIT-gitea-2021-45330","GHSA-pg38-r834-g45j","GO-2022-0982"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git hosting","requires_auth":"none","summary":"Attackers can reuse valid server-side sessions after client-side cookie deletion, leading to privilege escalation and account takeover in Gitea.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gitea","vendor":"gitea"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-459","name":"Incomplete Cleanup"}],"description":"An issue exsits in Gitea through 1.15.7, which could let a malicious user gain privileges due to client side cookies not being deleted and the session remains valid on the server side for reuse.","ecosystems":["Bitnami","Go"],"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":"Improper Privilege Management in Gitea","id":"CVE-2021-45330","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"gitea:gitea","products":["gitea:gitea"],"type":"auth_bypass","year":"2021"},"n_packages":4,"n_references":1,"next":{"headline":"Reuse of one time passwords allowed in Gitea","id":"CVE-2021-45331"},"packages":[{"ecosystem":"Bitnami","fixed":["1.15.8"],"introduced":["0"],"last_affected":[],"package":"gitea","purl":"pkg:bitnami/gitea","source":"BIT-gitea-2021-45330"},{"ecosystem":"Go","fixed":["1.6.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-pg38-r834-g45j"},{"ecosystem":"Go","fixed":["1.6.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-pg38-r834-g45j"},{"ecosystem":"Go","fixed":["1.6.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2022-0982"}],"prev":{"headline":"Cross-site Scripting in Gitea","id":"CVE-2021-45329"},"products":["n/a"],"published":"2022-02-09","related":[{"cvss_score":9.8,"headline":"Gitea Code Injection","id":"CVE-2026-60004","kev_date_added":"2026-08-25","published":"2026-08-26"},{"cvss_score":9.8,"headline":"Gitea WebAuthn bypass during OAuth and OIDC sign-in","id":"CVE-2026-73278","kev_date_added":null,"published":"2026-10-06"},{"cvss_score":9.8,"headline":"Gitea fork workflow approval bypass through maintainer-triggered events","id":"CVE-2026-94205","kev_date_added":null,"published":"2026-10-06"},{"cvss_score":9.8,"headline":"Gitea vulnerable to Argument Injection","id":"CVE-2022-42968","kev_date_added":null,"published":"2022-10-16"},{"cvss_score":9.8,"headline":"Reuse of one time passwords allowed in Gitea","id":"CVE-2021-45331","kev_date_added":null,"published":"2022-02-09"},{"cvss_score":9.8,"headline":"Capture-replay in Gitea","id":"CVE-2021-45327","kev_date_added":null,"published":"2022-02-08"}],"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":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":["n/a"]},"summary":"Attackers can reuse valid server-side sessions after client-side cookie deletion, leading to privilege escalation and account takeover in Gitea.","url":"https://insights.sbomify.com/CVE-2021-45330/"}
