Gitea Swift package manifest memory exhaustion

Summary

CVECVE-2026-63021
StatePUBLISHED
AssignerGitea
Source PriorityCVE Program / NVD first with legacy fallback
Published2026-10-14 15:17:21 UTC
Updated2026-10-14 16:17:47 UTC
DescriptionGitea'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.
