CVE-2026-62925 Details
Description
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.
A vulnerability exists in Gitea's Alpine package upload processing in versions through 1.27.2. The issue arises because the upload handler parses .apk files before applying any size quota checks. This lack of proper handling allows an authenticated user with package-publish permission to upload a small, highly compressed archive that expands into a large memory footprint. The unbounded parsing of the .PKGINFO data, particularly the 'provides=' and 'depend=' entries, can lead to significant memory consumption. In memory-limited environments, this may cause the Gitea process to be terminated or disrupt availability.
Users are advised to upgrade to Gitea version 1.27.3, where this vulnerability has been fixed. Instructions for upgrading can be found in the Gitea documentation.
