Name of the Vulnerable Software and Affected Versions
1Panel versions 2.0.13 and below
Description
1Panel is a web-based control panel for Linux server management. Versions 2.0.13 and below allow an unauthenticated attacker to bypass CAPTCHA verification by manipulating a client-controlled parameter. The server incorrectly trusts this parameter without validation, which allows attackers to disable CAPTCHA protections. This can lead to automated login attempts and potential account takeover (ATO).
Recommendations
Update to version 2.0.14 or later.
