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-2026-26232 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 1.25.5\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.25.5\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.25.5\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-2026-26232/ (Markdown: https://insights.sbomify.com/CVE-2026-26232/index.md)","id":"CVE-2026-26232","markdown":"https://insights.sbomify.com/CVE-2026-26232/index.md","name":"CVE-2026-26232","record":{"aliases":["GHSA-5v69-g2m3-3hq3","GO-2026-6336"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git Server","requires_auth":"none","summary":"Attackers can reuse expired OAuth2 authorization codes to bypass authentication and potentially take over user accounts in Gitea.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-294","name":"Authentication Bypass by Capture-replay"}],"description":"Gitea versions before 1.25.5 do not consistently enforce OAuth2 authorization code expiry and single-use behavior during token exchange.","ecosystems":["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":"Gitea OAuth2 authorization codes lack expiry and reuse enforcement","id":"CVE-2026-26232","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":3,"n_references":4,"next":{"headline":"Denial of Service via HTTP/2 single packet attack on login endpoint","id":"CVE-2026-26233"},"packages":[{"ecosystem":"Go","fixed":["1.25.5"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-5v69-g2m3-3hq3"},{"ecosystem":"Go","fixed":["1.25.5"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-5v69-g2m3-3hq3"},{"ecosystem":"Go","fixed":["1.25.5"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2026-6336"}],"prev":{"headline":"Gitea maintainer-edit permissions allow unauthorized commits to readable repositories","id":"CVE-2026-26231"},"products":["Gitea Open Source Git Server"],"published":"2026-07-03","related":[],"sources":[{"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-07","vendors":["Gitea"]},"summary":"Attackers can reuse expired OAuth2 authorization codes to bypass authentication and potentially take over user accounts in Gitea.","url":"https://insights.sbomify.com/CVE-2026-26232/"}
