CVE-2026-63021
CVE-2026-63021 updated by NVD
Summary
Gitea's Swift package parser limits each manifest to 128 KiB but does not limit the number of manifests or their aggregate size before reading them into memory. An authenticated user with package-publish permission can upload a highly compressed archive containing many manifests, causing allocations far larger than the uploaded archive. This can exhaust memory, terminate the process, or cause request failures.
