CVSScvssV3_1: 9.7

Nextcloud Global Site Selector is a tool used to run multiple small Nextcloud instances and redirect users to the right server. Security researchers have discovered a vulnerability in how it verifies user passwords that could allow hackers to authenticate as any user.

The flaw resides in the password verification method. By exploiting this, an attacker could bypass authentication and login as another user without knowing their actual password. This gives them access to private user data and accounts.

The good news is developers have released updates that fix the issue. Users running versions 1.4.1, 2.1.2, 2.3.4 or 2.4.5 are protected. If you have an older version, you are urged to upgrade immediately.

It’s always best to keep your software up-to-date as developers are constantly patching vulnerabilities. Take a few minutes to check for and install any updates to the Nextcloud Global Site Selector to shield yourself from would-be hackers aiming to access your accounts through authentication bypass attacks. Staying vigilant about your cybersecurity is important to prevent unauthorized access to sensitive personal and business information.
