description

Real 3D FlipBook versions through 5.5 are affected by an unauthenticated cross-site scripting issue. An unauthenticated attacker may be able to cause script execution in a user's browser; the available evidence does not identify the affected input or endpoint.

mitigation

No fixed version is recorded. Restrict public access to affected Real 3D FlipBook instances and apply vendor updates when a corrected release is available.
