Submit #749716: Vichan Devel Vichan 5.1.5 Unverified Password Changeinfo

TitleVichan Devel Vichan 5.1.5 Unverified Password Change
DescriptionAn authentication bypass in the password change mechanism (CWE-620) exists in vichan. An authenticated moderator can change their own password without supplying the current password. The application relies solely on an active session and permission checks, without re-authentication or password verification. If an attacker gains access to a valid moderator session (e.g., via XSS, CSRF, session fixation, or stolen cookies), they can permanently take over the account by changing the password.
