CVE-2025-52759Network attack vector

Reflected script execution via unneutralized request input

Published Jun 2, 2026 · Updated Jun 2, 2026

Reflected XSS in UnboundStudio Accordion FAQ 2.2.1 and earlier allows remote attackers to execute script in a victim's browser. Patchstack and the CNA record do not identify the affected request parameter, handler, or output context, leaving the precise neutralization failure undisclosed. Exploitation requires no account but requires a victim to open an attacker-crafted request, after which script runs within the affected site's browser origin.
