{"id":"CVE-2026-105268","summary":"Gitea issue attachment API allows changing comment attachments","details":"The Gitea API routes for issue attachments (`/api/v1/repos/{owner}/{repo}/issues/{index}/assets/{attachment_id}`) also accepted attachments that belong to comments on the issue. Because the author of an issue may edit and delete the issue's attachments, a user who opened an issue could rename or delete attachments that other users had posted in comments on that issue. The contents of the attachments could not be changed.","aliases":["GHSA-96qg-qxxj-r8xq"],"modified":"2026-10-08T02:50:30.608398027Z","published":"2026-10-06T21:35:40.926Z","database_specific":{"cna_assigner":"Gitea","cwe_ids":["CWE-639","CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105268.json"},"references":[{"type":"ADVISORY","url":"https://blog.gitea.com/release-of-28.1.0/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105268.json"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/releases/tag/v28.1.0"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-96qg-qxxj-r8xq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105268"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39501"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39507"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-gitea/gitea","events":[{"introduced":"0"},{"fixed":"4ebd5e319b6a9e629bfd7a04292a6fe85b08dee9"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"28.0.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v28.0.0","v29.0.0-dev","v1.28.0-dev","v1.27.0-dev","v1.26.0-dev","v1.25.0-dev","v1.24.0-dev","v1.22.0-rc1","v1.23.0-dev","v1.22.0-rc0","v1.21.0-rc0","v1.22.0-dev","v1.20.0-rc0","v1.21.0-dev","v1.20.0-dev","v1.19.0-rc0","v1.18.0-rc0","v1.19.0-dev","v1.18.0-dev","v1.17.0-dev","v1.16.0-rc1","v1.15.0-rc1","v1.16.0-dev","v1.15.0-dev","v1.14.0-dev","v1.13.0-dev","v1.12.0-dev","v1.10.5","v1.11.0-rc1","v1.10.0-rc1","v1.11.0-dev","v1.9.0-rc1","v1.10.0-dev","v1.9.0-dev","v1.7.0-dev","v1.6.0-rc1","v1.6.0-dev","v1.5.0-rc1","v1.5.0-dev","v1.1.0","v1.0.0","v0.9.99"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-105268.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}
