Recommendation: Monitor — no exploitation signal at the moment.

Horilla is an HR and CRM software. In 1.5.0, the notification endpoints trust the unvalidated next parameter and redirect users to arbitrary external URLs. This allows an attacker to turn trusted application links into phishing or social-engineering redirects.
