CVE-2026-56011 is an unauthenticated cross-site scripting (XSS) vulnerability in MapPress Maps for WordPress, specifically in versions up to 2.97.3. The vulnerability is due to improper neutralization of input during web page generation (CWE-79), allowing attackers to inject malicious scripts that can execute in the context of a victim's browser. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability at a low level. No patch or official remediation level has been published by the vendor as of the data provided.

Successful exploitation of this vulnerability could allow an unauthenticated attacker to execute arbitrary scripts in the context of users visiting affected WordPress sites using vulnerable versions of MapPress Maps. This can lead to partial compromise of confidentiality, integrity, and availability of the affected web application and potentially its users. The vulnerability requires user interaction but no authentication, increasing its risk profile.
