The WDesignKit WordPress plugin suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. This allows authenticated users with Contributor or higher privileges to inject arbitrary JavaScript into custom widgets. The malicious scripts execute in the context of any user who views the compromised page. The vulnerability affects all plugin versions up to 1.2.3. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and partial confidentiality and integrity impact. No patch or official remediation guidance is currently documented in the provided data.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via custom widgets. These scripts execute in the browsers of users who visit the infected pages, potentially leading to session hijacking, defacement, or other client-side attacks. The confidentiality and integrity of user data may be partially compromised. There is no indication of availability impact. No known exploits are reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should monitor for an official update from posimyththemes addressing this vulnerability. Until a patch is available, consider restricting Contributor-level access and above to trusted users only. Recreating custom widgets or reinstalling the plugin may be necessary once a fix is released to ensure full remediation.
