description

Nginx-UI releases without the fix allow an authenticated user to reset another user's password through the user-management interface without the required step-up session validation. An attacker with any valid account could use this to take control of an administrator account. Two-factor authentication on the target account does not prevent the affected password-reset path.

mitigation

Upgrade github.com/0xJacky/Nginx-UI to 1.9.10-0.20260703131214-23d1934099b0 or later. Until upgraded, restrict access to the Nginx-UI management interface and limit or remove untrusted user accounts.

fixed in 1.9.10-0.20260703131214-23d1934099b0
