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-2026-27761 exists.\n\nAffected packages and fixed versions:\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.26.3\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.26.3\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.26.3\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-2026-27761/ (Markdown: https://insights.sbomify.com/CVE-2026-27761/index.md)","id":"CVE-2026-27761","markdown":"https://insights.sbomify.com/CVE-2026-27761/index.md","name":"CVE-2026-27761","record":{"aliases":["GHSA-3pww-vcvm-3gmj","GO-2026-6031"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git Server","requires_auth":"low_privilege","summary":"Attackers can use API tokens lacking repository scope to access private commit data via RSS and Atom feed endpoints in Gitea.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Gitea versions up to and including 1.26.2 allow repository RSS and Atom feed endpoints to bypass API access token scope checks, exposing private repository commit data to tokens without the required repository scope.","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 repository feeds bypass API token scope enforcement","id":"CVE-2026-27761","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":3,"n_references":4,"next":{"headline":"Mobiliti e-mobi.hu Insufficient Session Expiration","id":"CVE-2026-27764"},"packages":[{"ecosystem":"Go","fixed":["1.26.3"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-3pww-vcvm-3gmj"},{"ecosystem":"Go","fixed":["1.26.3"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-3pww-vcvm-3gmj"},{"ecosystem":"Go","fixed":["1.26.3"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2026-6031"}],"prev":{"headline":"OpenCATS PHP Code Injection via installer AJAX endpoint","id":"CVE-2026-27760"},"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 can use API tokens lacking repository scope to access private commit data via RSS and Atom feed endpoints in Gitea.","url":"https://insights.sbomify.com/CVE-2026-27761/"}
