CVE-2024-13395 is a stored cross-site scripting vulnerability in the Threepress WordPress plugin by kerryoco. The flaw exists in the handling of the 'threepress' shortcode, where user-supplied attributes are not properly sanitized or escaped before being rendered on web pages. This allows authenticated users with contributor or higher privileges to inject arbitrary JavaScript that executes in the context of other users viewing the page. The vulnerability affects all versions up to and including 1.7.1. The CVSS 3.1 base score is 6.4 (medium), reflecting network attack vector, low attack complexity, privileges required, no user interaction, and impacts on confidentiality and integrity but not availability.

An attacker with contributor-level access or higher can inject persistent malicious scripts into pages using the vulnerable shortcode. This can lead to unauthorized actions performed in the context of other users, data theft, or session hijacking. The impact affects confidentiality and integrity but does not affect availability. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only. Monitor for plugin updates from the vendor and apply official patches once released. Avoid using the 'threepress' shortcode with untrusted input.
