CVE-2025-4567Public exploitNetwork attack vector

Stored XSS via unescaped Query Offset

Published Jun 3, 2025 · Updated Jun 3, 2025

Stored XSS in InfornWeb Post Slider and Post Carousel before 3.2.10 allows remote authenticated users to run script in a viewer's browser. The PSAC Post Vertical Slider Widget writes its stored Query Offset value into the widget editor field without validation or output escaping. Contributor-level access is sufficient to store a payload; execution requires another user to edit the widget and interact with the injected field.
