CVE-2024-13736 is a stored cross-site scripting vulnerability in the Pure Chat – Live Chat & More! WordPress plugin affecting all versions up to and including 2.4. The vulnerability is due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of the 'purechatWidgetName' parameter. This allows unauthenticated attackers to inject arbitrary web scripts that execute in the context of users visiting the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS 3.1 score of 6.1 (medium severity) with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts confidentiality and integrity but not availability.

Successful exploitation can lead to execution of arbitrary scripts in the context of users visiting affected pages, potentially compromising user confidentiality and integrity. There is no direct impact on availability. The vulnerability can be exploited by unauthenticated attackers but requires user interaction (visiting the injected page). No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are currently available. Until a patch is released, users should consider disabling or removing the plugin if possible or applying manual mitigations such as input validation or output encoding if feasible.
