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-2026-56443 exists.\n\nAffected packages and fixed versions:\n- gitea.dev (Go): affected all versions; fixed in 1.27.0\n- gitea.dev (Go): affected all versions; fixed in 1.27.0\n- gitea.dev (Go): affected all versions; fixed in 1.27.0\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.27.0\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.27.0\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-2026-56443/ (Markdown: https://insights.sbomify.com/CVE-2026-56443/index.md)","id":"CVE-2026-56443","markdown":"https://insights.sbomify.com/CVE-2026-56443/index.md","name":"CVE-2026-56443","record":{"aliases":["GHSA-7p4h-3gxq-x3h3","GO-2026-6045","MINI-62rp-9f5m-j6w5","MINI-fpcm-f4p6-fwgw"],"analysis":{"component_type":"server_software","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 bypass token public-only scope restrictions to access limited-visibility repositories and packages in Gitea.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":9.6,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Token public-only scope bypassed on Limited-visibility owners (Repository + Package categories) — residual after CVE-2026-25714 / PR #37118","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: Token public-only scope bypassed on Limited-visibility owners (Repository + Package categories) — residual after CVE-2026-25714 / PR #37118","id":"CVE-2026-56443","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":5,"n_references":3,"next":{"headline":"Denial of service in Unbound","id":"CVE-2026-56444"},"packages":[{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-7p4h-3gxq-x3h3"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-7p4h-3gxq-x3h3"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"gitea.dev","purl":null,"source":"GHSA-7p4h-3gxq-x3h3"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"gitea.dev","purl":"pkg:golang/gitea.dev","source":"GHSA-7p4h-3gxq-x3h3"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"gitea.dev","purl":"pkg:golang/gitea.dev","source":"GO-2026-6045"}],"prev":{"headline":"Uncontrolled search path element issue exists in Pupsman versions prior to 3.9.0.","id":"CVE-2026-56437"},"products":["Gitea Open Source Git Server"],"published":"2026-08-13","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":"2026-08-14","vendors":["Gitea"]},"summary":"Attackers can bypass token public-only scope restrictions to access limited-visibility repositories and packages in Gitea.","url":"https://insights.sbomify.com/CVE-2026-56443/"}
