CVE-2023-3933Network attack vector

Reflected XSS via client-side prototype pollution

Published Oct 20, 2023 · Updated Apr 8, 2026

Reflected XSS in the Wiloke YourJourney theme 1.9.8 and earlier allows remote attackers to inject scripts through crafted links. Published materials do not identify the affected parameter or code path; they state that client-side prototype pollution combines with insufficient input sanitization and output escaping. Exploitation requires a victim to follow an attacker-controlled link, after which the injected script executes in the victim's browser context and can read or alter page-accessible data.
