Unauthenticated File Upload in Gogs Enables Arbitrary Hosting

Publication date: 2026-02-19

Last updated on: 2026-02-19

Assigner: GitHub, Inc.

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.

Executive Summary

This vulnerability affects Gogs, an open source self-hosted Git service, in versions 0.13.4 and below. When the global RequireSigninView setting is disabled (which is the default), any remote user can upload arbitrary files to the server through unauthenticated file upload endpoints located at /releases/attachments and /issues/attachments.

Because these endpoints are exposed without authentication, attackers can abuse the instance as a public file host. This can lead to issues such as disk exhaustion, hosting unwanted content, or delivering malware. Additionally, CSRF tokens do not prevent this attack due to the way same-origin cookies are issued.

This vulnerability was fixed in version 0.14.1 of Gogs.

Impact Analysis

This vulnerability can impact you by allowing unauthorized users to upload arbitrary files to your Gogs server. This can result in several negative consequences:

  • Disk exhaustion due to uncontrolled file uploads, potentially causing denial of service.
  • Hosting of malicious or unwanted content on your server, which could damage your reputation or violate policies.
  • Delivery of malware to users who access the uploaded files, leading to security risks for your users.
