CVE-2026-56011Network attack vector

Unauthenticated browser script execution

Published Jun 26, 2026 · Updated Jun 26, 2026

XSS in MapPress Maps for WordPress 2.97.3 and earlier allows remote attackers to run scripts in a visitor's browser via unspecified input. The public record does not identify the vulnerable parameter or code path; the vendor changelog states only that 2.97.4 adds escaping in an iframe. Exploitation is unauthenticated but requires a privileged user to open attacker-controlled content, exposing browser-session data and actions within that user's site privileges.
