{"id":"CVE-2026-110494","summary":"Gitea release attachment re-linking of issue attachments","details":"Adding attachments to a release checked the repository and release of an attachment but not whether it was already linked to an issue or comment. A user with write access to the releases of a repository, who knew the UUID of an attachment in that repository, could link it to a release. This exposed the file name, size and download count of the attachment through the release and allowed the user to rename or delete it.","aliases":["GHSA-cwq7-782w-pxcc"],"modified":"2026-10-19T10:45:17.857001643Z","published":"2026-10-18T18:57:26.290Z","database_specific":{"cna_assigner":"Gitea","cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110494.json"},"references":[{"type":"ADVISORY","url":"https://blog.gitea.com/release-of-28.2.0/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110494.json"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39839"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39847"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/releases/tag/v28.2.0"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-cwq7-782w-pxcc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110494"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-gitea/gitea","events":[{"introduced":"0"},{"last_affected":"4ebd5e319b6a9e629bfd7a04292a6fe85b08dee9"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"28.1.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v28.1.0","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-2026-110494.json"}}],"schema_version":"1.9.0"}
