What is CVE-2026-25242?

Gogs, an open-source self-hosted Git service, has a significant security vulnerability that allows unauthenticated file uploads on versions 0.13.4 and earlier. By default, when the 'RequireSigninView' setting is disabled, any user can upload arbitrary files via the endpoints /releases/attachments and /issues/attachments. This improper validation exposes the system to potential misuse, enabling it to function as a public file host, which may lead to issues such as disk exhaustion, content hosting risks, or even the delivery of malicious files. The vulnerability is addressed in Gogs version 0.14.1.
