Upgrade Gitea to version 28.4.0 or later, where the cleanup logic has been corrected to only remove blobs created by failed uploads. No other mitigation is required as the issue is fixed in this official release.

Description

CVE-2026-120991 is a vulnerability in Gitea where improper cleanup on a failed container blob upload could remove shared blob content used by other packages. This could cause other users' packages or image layers with identical content to become undownloadable if a package size quota is exceeded. The issue affects Gitea versions from 1.20.0 up to but not including 28.4.0. The vulnerability has been fixed in version 28.4.0 by changing the cleanup process to only remove blobs created by the failed upload.
