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-2026-28699 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-2026-28699/ (Markdown: https://insights.sbomify.com/CVE-2026-28699/index.md)","id":"CVE-2026-28699","markdown":"https://insights.sbomify.com/CVE-2026-28699/index.md","name":"CVE-2026-28699","record":{"aliases":["GHSA-9r5x-wg6m-x2rc","GO-2026-5299"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Gitea Git Server","requires_auth":"low_privilege","summary":"Attackers can bypass OAuth2 access token scope restrictions by using HTTP Basic authentication, potentially gaining unauthorized access to resources.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Gitea versions up to and including 1.26.1 allow OAuth2 access token scope enforcement to be bypassed through HTTP Basic authentication.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":"2026-06-11","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-06-11T02:23:10Z","kind":"github_poc","ref":"https://github.com/Alardiians/gitea-CVE-2026-28699","stars":1,"title":"Lab + writeup for CVE-2026-28699: Gitea OAuth2 scope enforcement bypass via HTTP Basic auth"}],"tier":"weaponised"},"has_fix":true,"headline":"Gitea Basic Auth bypasses OAuth2 access token scopes","id":"CVE-2026-28699","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":"Privilege escalation in EquiTriton","id":"CVE-2026-28700"},"packages":[{"ecosystem":"Go","fixed":["1.26.2"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":null,"source":"GHSA-9r5x-wg6m-x2rc"},{"ecosystem":"Go","fixed":["1.26.2"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GHSA-9r5x-wg6m-x2rc"},{"ecosystem":"Go","fixed":["1.26.2"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2026-5299"}],"prev":{"headline":"Exposure of Sensitive System Information to an Unauthorized Control Sphere in Panduit IntraVUE by Pronetiqs","id":"CVE-2026-28698"},"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":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-06","vendors":["Gitea"]},"summary":"Attackers can bypass OAuth2 access token scope restrictions by using HTTP Basic authentication, potentially gaining unauthorized access to resources.","url":"https://insights.sbomify.com/CVE-2026-28699/"}
