Vulnerabilities
- Medium 6.4
CVE-2026-0556contributor+≤ 3.2.10
XO Event Calendar <= 3.2.10 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'xo_event_field' shortcode
The access label is read from the record's own text (e.g. “subscriber+”: subscriber and above). When the text names no role, CVSS decides between “login required” and “high privilege”; no role name is invented. “Needs a click”: the attack depends on a logged-in user following a link (CSRF, reflected XSS).
