Detailsinfo

A vulnerability has been found in Gitea up to 1.27.2 and classified as problematic. Affected by this vulnerability is an unknown code block of the component Downloader. The manipulation with an unknown input leads to a resource consumption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect availability. The summary by CVE is:

Gitea's OneDev migration downloader reads the entire remote version response into memory without a size limit and uses a client without a timeout. An authenticated user who can start a repository migration can direct it to an attacker-controlled OneDev-compatible server returning an oversized or never-ending response. This can consume memory and hold migration workers, impairing service availability.
