Published: 2026-10-18 · updated 2026-10-19
Weakness: CWE-200

Description

The visibility check of Gitea user profiles was applied to GET requests only, while `POST /{username}` (follow and unfollow) required only a signed-in user. Any authenticated user could therefore obtain the full name, location, website and description of a user with a private profile from the response. The issue was fixed in 28.1.0 and disclosed with 28.2.0.

Affected products

Gitea Open Source Git Server: from 1.22.0 through 28.0.0
