WordPress GDPR & CCPA < 1.9.27 - Unauthenticated Reflected Cross-Site Scripting

published 2022-02-01 4 y ago modified 2026-06-17 4 mo ago also EUVD-2022-15421

cvss: 6.1; version 3.1, NVD
cisa kev: Not listed; not in CISA's catalog
epss: 2.3%; EPSS 2.3% chance of exploitation in 30 days, percentile 83%
public exploits: 0; none known, plus a Nuclei check

The check_privacy_settings AJAX action of the WordPress GDPR WordPress plugin before 1.9.27, available to both unauthenticated and authenticated users, responds with JSON data without an "application/json" content-type. Since an HTML payload isn't properly escaped, it may be interpreted by a web browser led to this endpoint. Javascript code may be executed on a victim's browser. Due to v1.9.26 adding a CSRF check, the XSS is only exploitable against unauthenticated users (as they all share the same nonce)
