Name of the Vulnerable Software and Affected Versions Perx Customer Engagement & Loyalty Platform versions prior to 4.617.4

Description A stored cross-site scripting (XSS) issue exists in the LMT Dashboard of the Perx Customer Engagement & Loyalty Platform. This allows an authenticated attacker to execute arbitrary JavaScript code in a victim’s browser. The issue is caused by insufficient sanitization of SVG file uploads. An attacker can upload a malicious SVG file containing a script payload to a campaign. When another user views this image on the public LMT microsite, the script executes, potentially leading to session hijacking or data theft. The vulnerability involves uploading a malicious SVG file, which then executes a script when viewed.

Recommendations Versions prior to 4.617.4 should be updated.
