CVE-2026-1941 is a stored cross-site scripting vulnerability in the WP Event Aggregator plugin for WordPress, affecting all versions up to 1.8.7. The vulnerability exists due to improper neutralization of input in the 'wp_events' shortcode, where user-supplied attributes are not properly sanitized or escaped before output. Authenticated attackers with Contributor-level privileges or higher can exploit this to inject arbitrary JavaScript that executes in the context of any user viewing the injected page. The vulnerability has a CVSS 3.1 score of 6.4, reflecting a medium severity with potential confidentiality and integrity impacts but no availability impact. No known exploits in the wild or official patches are documented in the provided information.

Successful exploitation allows an authenticated user with Contributor-level or higher privileges to inject and store malicious scripts that execute in the browsers of users who view the affected pages. This can lead to unauthorized actions performed on behalf of users, theft of sensitive information, or session hijacking. The impact affects confidentiality and integrity but does not affect availability. There is no indication of active exploitation in the wild.

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 limiting use of the 'wp_events' shortcode. Implement additional input validation or output escaping via custom code or security plugins as a temporary mitigation.
