CVE-2025-0507 is a stored cross-site scripting vulnerability in the Ticketmeo – Sell Tickets – Event Ticketing WordPress plugin (versions up to 2.3.6). The issue stems from improper neutralization of input during web page generation, specifically insufficient sanitization and output escaping of user-supplied shortcode attributes. Authenticated attackers with contributor-level permissions or higher can inject arbitrary JavaScript code that executes in the context of users viewing the injected pages. This vulnerability can lead to information disclosure or session hijacking but does not affect availability. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and partial impact on confidentiality and integrity.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via shortcode attributes. These scripts execute in the browsers of users who visit the compromised pages, potentially leading to theft of sensitive information or session tokens. The vulnerability does not impact system availability. There are no reports 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 removing the Ticketmeo plugin if possible. Monitor for updates from the vendor or WordPress plugin repository to apply any forthcoming patches promptly.
