{"answers":{"affected":"5 open source packages ship an affected version, including gitea.dev and code.gitea.io/gitea.","exploited":"It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-56657 exists.","fix":"Upgrade gitea.dev to 1.27.0 or later.","what":"CVE-2026-56657 is a medium-severity vulnerability in Gitea Open Source Git Server, published on 13 Aug 2026."},"fix_prompt":"Check this codebase for CVE-2026-56657 and fix it if it is affected.\n\nWhat it is: CVE-2026-56657 is a medium-severity vulnerability in Gitea Open Source Git Server, published on 13 Aug 2026. \nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-56657 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-2026-56657/ (Markdown: https://insights.sbomify.com/CVE-2026-56657/index.md)","id":"CVE-2026-56657","markdown":"https://insights.sbomify.com/CVE-2026-56657/index.md","name":"CVE-2026-56657","record":{"aliases":["GHSA-4xjf-493q-98p3","GO-2026-6042","MINI-2w3f-f592-993f","MINI-crrj-qppm-2mvg"],"analysis":null,"analysis_generated_by":null,"assigner":"Gitea","cpe":[],"cvss":{"score":6.2,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Gitea SSH Key Parser Denial of Service","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 SSH Key Parser Denial of Service","id":"CVE-2026-56657","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":null,"year":"2026"},"n_packages":5,"n_references":3,"next":{"headline":"GetSimple CMS: CSRF, SSRF, and Unrestricted Zip Extraction","id":"CVE-2026-56660"},"packages":[{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-4xjf-493q-98p3"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-4xjf-493q-98p3"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"gitea.dev","purl":null,"source":"GHSA-4xjf-493q-98p3"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"gitea.dev","purl":"pkg:golang/gitea.dev","source":"GHSA-4xjf-493q-98p3"},{"ecosystem":"Go","fixed":["1.27.0"],"introduced":["0"],"last_affected":[],"package":"gitea.dev","purl":"pkg:golang/gitea.dev","source":"GO-2026-6042"}],"prev":{"headline":"Privilege Escalation via Access Token Scope Escalation in API","id":"CVE-2026-56654"},"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":"2026-08-13","vendors":["Gitea"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-56657/"}
