This vulnerability involves improper input sanitization in the Events Manager – OpenStreetMaps plugin by Stonehenge Creations, leading to stored cross-site scripting (XSS). An attacker could inject malicious scripts that are stored and later executed when other users access the affected web pages. The CVSS vector indicates the attack requires network access, low attack complexity, privileges, and user interaction, with impacts on confidentiality, integrity, and availability rated as low to low-medium. The affected versions include all versions up to 4.2.1. No official patch or remediation details are currently available.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of users viewing the affected pages, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability. The medium severity score reflects these moderate risks. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider applying input validation or output encoding workarounds if feasible.
