What is CVE-2025-69413?

In Gitea versions before 1.25.2, the API endpoint /api/v1/user exhibits inconsistent authentication responses based on whether the given username exists in the system. This can lead to potential attackers gaining information about valid usernames, which could facilitate further attacks on user accounts. It is crucial for administrators to upgrade to version 1.25.2 or later to mitigate this security issue.
