Unauthenticated visitor redirection via decoded request paths
Published Aug 4, 2026 · Updated Aug 4, 2026
Open redirect in Creativemotion Clearfy Cache before 2.4.3 allows remote attackers to redirect visitors via a crafted URL. The Cyrlitera old-URL handler decodes the request path and passes the result to an unsafe redirect function without validating the destination host. Exploitation requires the non-default old-URL redirection option and visitor interaction with the crafted link; the result is redirection to an attacker-chosen external site.
