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-2026-27771 exists.\n\nAffected packages and fixed versions:\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.26.2\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.26.2\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.26.2\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-2026-27771/ (Markdown: https://insights.sbomify.com/CVE-2026-27771/index.md)","id":"CVE-2026-27771","markdown":"https://insights.sbomify.com/CVE-2026-27771/index.md","name":"CVE-2026-27771","record":{"aliases":["GHSA-8qw8-rq86-9pc2","GO-2026-6017"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git Server","requires_auth":"none","summary":"Attackers can access private or internal Composer package source information due to insufficient permission checks in Gitea.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Gitea versions up to and including 1.26.1 have insufficient permission checks for Composer package source links, which can expose private or internal package source information.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":"2026-05-27","github_poc":2,"max_poc_stars":19,"metasploit":0,"nuclei":1,"refs":[{"date":"2026-05-27T15:54:41Z","kind":"github_poc","ref":"https://github.com/portbuster1337/CVE-2026-27771","stars":19,"title":"CVE-2026-27771 - Gitea/Forgejo Container Registry Auth Bypass Exploit PoC - Pull private container images without authentication"},{"date":"2026-05-27T15:14:41Z","kind":"github_poc","ref":"https://github.com/HORKimhab/CVE-2026-27771","stars":0,"title":"CVE-2026-27771"},{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-27771.yaml","stars":null,"title":"Gitea Container Registry - Unauthorized Private Image Access"}],"tier":"weaponised"},"has_fix":true,"headline":"Gitea Composer package source links use insufficient permission checks","id":"CVE-2026-27771","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":"EV Energy ev.energy Missing Authentication for Critical Function","id":"CVE-2026-27772"},"packages":[{"ecosystem":"Go","fixed":["1.26.2"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-8qw8-rq86-9pc2"},{"ecosystem":"Go","fixed":["1.26.2"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-8qw8-rq86-9pc2"},{"ecosystem":"Go","fixed":["1.26.2"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2026-6017"}],"prev":{"headline":"ePower epower.ie Insufficiently Protected Credentials","id":"CVE-2026-27770"},"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-07","vendors":["Gitea"]},"summary":"Attackers can access private or internal Composer package source information due to insufficient permission checks in Gitea.","url":"https://insights.sbomify.com/CVE-2026-27771/"}
