Detailsinfo

A vulnerability classified as problematic has been found in Gitea up to 1.27.2. Affected is an unknown code block of the component Maven Upload Handler. The manipulation with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. This is going to have an impact on availability. CVE summarizes:

Gitea's Maven upload handler reads checksum uploads entirely into memory and returns before enforcing package-size quotas. An authenticated user with package-publish permission can submit an oversized body to a checksum endpoint despite legitimate checksum values being at most 128 bytes. This bypasses the upload quota on that path and can exhaust server memory.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-73273 since 08/13/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1499.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
