Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-26231 exists.\n\nAffected packages and fixed versions:\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.26.2\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.26.2\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.26.2\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-2026-26231/ (Markdown: https://insights.sbomify.com/CVE-2026-26231/index.md)","id":"CVE-2026-26231","markdown":"https://insights.sbomify.com/CVE-2026-26231/index.md","name":"CVE-2026-26231","record":{"aliases":["GHSA-mm7c-rhg6-qr4r","GO-2026-5510"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git Server","requires_auth":"low_privilege","summary":"Attackers with read access can push unauthorized commits to repositories due to flawed maintainer edit permission checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Gitea versions up to and including 1.26.1 allow the Allow edits from maintainers permission path to authorize commits to repositories that the user can read but should not be able to write.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Gitea maintainer-edit permissions allow unauthorized commits to readable repositories","id":"CVE-2026-26231","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":3,"n_references":5,"next":{"headline":"Gitea OAuth2 authorization codes lack expiry and reuse enforcement","id":"CVE-2026-26232"},"packages":[{"ecosystem":"Go","fixed":["1.26.2"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-mm7c-rhg6-qr4r"},{"ecosystem":"Go","fixed":["1.26.2"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-mm7c-rhg6-qr4r"},{"ecosystem":"Go","fixed":["1.26.2"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2026-5510"}],"prev":{"headline":"Team Admin Privilege Escalation to Demote Members to Guest","id":"CVE-2026-26230"},"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-07","vendors":["Gitea"]},"summary":"Attackers with read access can push unauthorized commits to repositories due to flawed maintainer edit permission checks.","url":"https://insights.sbomify.com/CVE-2026-26231/"}
