The LatePoint WordPress plugin suffers from a stored XSS vulnerability via the 'id' parameter of the 'latepoint_resources' shortcode. This occurs because the plugin fails to properly neutralize input during web page generation, allowing authenticated users with Contributor or higher privileges to inject malicious scripts. These scripts execute in the context of users who access the injected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to 5.1.94. There is no vendor advisory or patch information provided, and no known exploits in the wild have been reported.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable parameter. This can lead to the execution of arbitrary JavaScript in the context of other users viewing the affected pages, potentially compromising user sessions or performing unauthorized actions. The impact is limited to confidentiality and integrity with no direct availability impact. The vulnerability requires authenticated access, reducing the attack surface compared to unauthenticated XSS.

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 'latepoint_resources' shortcode if feasible. Monitor official LatePoint plugin channels for updates and apply patches promptly once released.
