CVE-2024-12452 is a stored cross-site scripting vulnerability in the Ziggeo WordPress plugin (versions up to 3.1). It occurs due to improper neutralization of input during web page generation, specifically in the 'ziggeo_event' shortcode, where user-supplied attributes are not properly sanitized or escaped. Authenticated attackers with contributor or higher privileges can inject arbitrary JavaScript that executes in the context of users visiting the injected page. This vulnerability can lead to information disclosure or session hijacking but does not impact availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, privileges required, no user interaction, and scope change.

An attacker with contributor-level or higher access can inject malicious scripts that execute in the browsers of users viewing the affected pages. This can lead to information disclosure or unauthorized actions performed in the context of the victim user. There is no indication of impact on system availability. The vulnerability affects confidentiality and integrity to a limited extent.

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