CVE-2026-62925

Gitea parses Alpine package uploads before enforcing package-size quotas and does not bound the decompressed .PKGINFO data or its dependency and provides entry counts. An authenticated user with package-publish permission can upload a small, highly compressed archive that causes disproportionately large memory allocations during parsing and metadata generation. On memory-constrained deployments, this can terminate the process or otherwise disrupt availability.
