CVE-2025-9205 describes a stored cross-site scripting vulnerability in the MapSVG plugin for WordPress, affecting all versions up to and including 8.14.0. The issue is caused by improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of user-supplied attributes in map options. This flaw enables authenticated attackers with contributor-level privileges or higher to inject arbitrary scripts that execute in the context of users viewing the compromised pages. The vulnerability has a CVSS 3.1 base score of 6.4 (medium severity), with network attack vector, low attack complexity, privileges required at the low level, no user interaction needed, and impacts confidentiality and integrity with no availability impact.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages using the MapSVG plugin, leading to potential compromise of user confidentiality and integrity when other users access the injected content. This could result in session hijacking, unauthorized actions, or data exposure within the affected WordPress site context. There is no indication of availability impact or known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the MapSVG plugin if possible. Monitor vendor channels for updates and apply patches promptly once released.
