Open redirect via unsanitized URL tags
Published May 1, 2024 · Updated May 30, 2025
Open redirect in ViewerJS 0.5.8 allows remote attackers to redirect users and trigger external resource requests via crafted URL tags. The URL-tag handler accepts an unsanitized document location and supplies it to browser navigation and content-loading paths. A user must open a crafted ViewerJS link; the redirect changes browser navigation, while the resource load produces attacker-observable traffic.
