description

Popup Maker versions through 1.23.0 are affected by a DOM-based cross-site scripting issue. An unauthenticated attacker may cause script to run in a victim's browser when the victim interacts with affected content.

mitigation

Disable or remove Popup Maker from affected sites until a corrected vendor release is available. No fixed version is recorded in the advisory; monitor for and promptly apply the vendor update when published.
