Lifecycle Timeline
3DescriptionGitHub Advisory
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 ViewAI
Gogs instances running version 0.13.4 or below are vulnerable to unauthenticated file uploads, allowing attackers to execute arbitrary code without credentials. Any organization operating self-hosted Gogs repositories is at immediate risk of complete system compromise and potential lateral movement into connected infrastructure.
Apply vendor patch. If patching is delayed: implement network-level access controls to restrict unauthenticated traffic to upload endpoints; deploy Web Application Firewall rules to block POST requests to file upload paths from untrusted sources; disable or isolate the affected Gogs service until patching is complete; enforce authentication requirements at reverse proxy layer.
