CVE-2025-12976 is a stored cross-site scripting vulnerability in the Events Manager – Calendar, Bookings, Tickets, and more! WordPress plugin by netweblogic. The flaw exists in the 'events_list_grouped' shortcode due to improper neutralization of input, allowing authenticated contributors and above to inject malicious scripts. These scripts execute in the context of users who visit the injected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to 7.2.2.1. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, no user interaction, and impacts confidentiality and integrity with no availability impact.

An authenticated attacker with contributor-level permissions or higher can exploit this vulnerability to inject persistent malicious scripts into pages generated by the plugin. These scripts execute in the browsers of users who access the compromised pages, potentially exposing sensitive information or enabling further attacks. The impact affects confidentiality and integrity but does not affect 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 released, restrict contributor-level access to trusted users only and consider disabling or removing the vulnerable plugin if possible. Monitor official vendor channels for updates and apply patches promptly once available.
