Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-28740 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitea.dev (Go): affected all versions; fixed in 1.26.3\n- gitea.dev (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-2026-28740/ (Markdown: https://insights.sbomify.com/CVE-2026-28740/index.md)","id":"CVE-2026-28740","markdown":"https://insights.sbomify.com/CVE-2026-28740/index.md","name":"CVE-2026-28740","record":{"aliases":["GHSA-2m9v-5q2g-58vq","GO-2026-6029"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git Server","requires_auth":"low_privilege","summary":"Attackers with repository access but no Code-unit permission can read private source objects via Git LFS reuse in Gitea.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Gitea versions up to and including 1.26.2 allow Git LFS object reuse to authorize private source objects for users who have repository access but lack Code-unit access.","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 LFS object reuse bypasses Code-unit authorization","id":"CVE-2026-28740","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":"CSRF Protection Bypass Allows Updating a User's Authentication Method","id":"CVE-2026-28741"},"packages":[{"ecosystem":"Go","fixed":["1.26.3"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2026-6029"},{"ecosystem":"Go","fixed":["1.26.3"],"introduced":["0"],"last_affected":[],"package":"gitea.dev","purl":null,"source":"GHSA-2m9v-5q2g-58vq"},{"ecosystem":"Go","fixed":["1.26.3"],"introduced":["0"],"last_affected":[],"package":"gitea.dev","purl":"pkg:golang/gitea.dev","source":"GHSA-2m9v-5q2g-58vq"}],"prev":{"headline":"Gitea 3D file viewer allows stored XSS through glTF extensionsRequired","id":"CVE-2026-28737"},"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-07","vendors":["Gitea"]},"summary":"Attackers with repository access but no Code-unit permission can read private source objects via Git LFS reuse in Gitea.","url":"https://insights.sbomify.com/CVE-2026-28740/"}
