Summary

1Panel versions 2.0.13 and below allow an unauthenticated attacker to disable CAPTCHA verification by abusing a client-controlled parameter. Because the server trusted this value without proper validation, CAPTCHA protections can be bypassed, enabling automated login attempts and significantly increasing the risk of account takeover (ATO). This issue is fixed in version 2.0.14.

Risk Assessment

Bypassing CAPTCHA significantly increases the risk of account takeover (ATO) through automated brute-force attacks on passwords. Organizations using 1Panel are exposed to unauthorized access to the server management panel.

Recommendation

Update 1Panel to version 2.0.14 or later. Until patched, consider restricting panel access from untrusted networks.
