An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-58443 exists.\n\nAffected packages and fixed versions:\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- gitea.dev (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-2026-58443/ (Markdown: https://insights.sbomify.com/CVE-2026-58443/index.md)","id":"CVE-2026-58443","markdown":"https://insights.sbomify.com/CVE-2026-58443/index.md","name":"CVE-2026-58443","record":{"aliases":["GHSA-xxjv-752h-3vp2","GO-2026-6086","MINI-hfx3-rx4f-9c7h","MINI-pqcv-mgj7-j32f"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git Server","requires_auth":"none","summary":"Attackers with public-only repository tokens can modify private pull request head branches, compromising data integrity in Gitea.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Public-only repository tokens can update private PR head branches","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":"Public-only repository tokens can update private PR head branches","id":"CVE-2026-58443","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":3,"n_references":3,"next":{"headline":"Gitea: Personal access token scope enforcement bypass on the repository home page (`GET /{owner}/{repo}`) discloses private repository contents","id":"CVE-2026-58444"},"packages":[{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-xxjv-752h-3vp2"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-xxjv-752h-3vp2"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"gitea.dev","purl":"pkg:golang/gitea.dev","source":"GO-2026-6086"}],"prev":{"headline":"Repository migration SSRF via multi-answer DNS allow-list bypass","id":"CVE-2026-58442"},"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-14","vendors":["Gitea"]},"summary":"Attackers with public-only repository tokens can modify private pull request head branches, compromising data integrity in Gitea.","url":"https://insights.sbomify.com/CVE-2026-58443/"}
