Unauthenticated victim-browser script execution
Published Dec 18, 2025 · Updated Dec 18, 2025
Reflected XSS in 8theme XStore Core before 5.6 allows remote attackers to execute script in a visitor's browser via a crafted link. Patchstack has not published the affected request parameter, endpoint, or code path; the record states only that untrusted input is reflected without safe neutralization. No authentication is required, but a user must follow the crafted link, and the resulting script runs in that user's site context.
