Every CVE for Gitea

Exploited in the last 30 days

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.
