CVE-2026-25242 Gogs allows unauthenticated file uploads

What is CVE-2026-25242?

CVE-2026-25242 is a medium-severity missing authorization vulnerability in gogs, published on 19 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

Gogs is an open source self-hosted Git service. Versions 0.13.4 and below expose unauthenticated file upload endpoints by default. When the global RequireSigninView setting is disabled (default), any remote user can upload arbitrary files to the server via /releases/attachments and /issues/attachments. This enables the instance to be abused as a public file host, potentially leading to disk exhaustion, content hosting, or delivery of malware. CSRF tokens do not mitigate this attack due to same-origin cookie issuance. This issue has been fixed in version 0.14.1.

Weakness: CWE-862
