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-2026-58423 exists.\n\nAffected packages and fixed versions:\n- code.gitea.io/gitea (Go): affected from 1.23.0; fixed in 1.26.3\n- code.gitea.io/gitea (Go): affected from 1.23.0; fixed in 1.26.3\n- code.gitea.io/gitea (Go): affected from 1.23.0; 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-2026-58423/ (Markdown: https://insights.sbomify.com/CVE-2026-58423/index.md)","id":"CVE-2026-58423","markdown":"https://insights.sbomify.com/CVE-2026-58423/index.md","name":"CVE-2026-58423","record":{"aliases":["GHSA-7wvc-rvp7-w99x","GO-2026-6046"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Git server","requires_auth":"low_privilege","summary":"Attackers can bypass authentication via malformed SSH sub-verbs to read private repositories in Gitea Git servers.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"LFS authentication bypass via malformed SSH sub-verb allows unauthorized read access to private repositories","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":"LFS authentication bypass via malformed SSH sub-verb allows unauthorized read access to private repositories","id":"CVE-2026-58423","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":3,"n_references":4,"next":{"headline":"Permanent Fork PR Workflow Approval Gate Bypass","id":"CVE-2026-58424"},"packages":[{"ecosystem":"Go","fixed":["1.26.3"],"introduced":["1.23.0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-7wvc-rvp7-w99x"},{"ecosystem":"Go","fixed":["1.26.3"],"introduced":["1.23.0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-7wvc-rvp7-w99x"},{"ecosystem":"Go","fixed":["1.26.3"],"introduced":["1.23.0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2026-6046"}],"prev":{"headline":"Improper authorization on OAuth sign-in callback silently re-enables administrator-disabled accounts","id":"CVE-2026-58422"},"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":"2026-07-06","vendors":["Gitea"]},"summary":"Attackers can bypass authentication via malformed SSH sub-verbs to read private repositories in Gitea Git servers.","url":"https://insights.sbomify.com/CVE-2026-58423/"}
