CVE-2024-1761 is a stored cross-site scripting vulnerability in the ninjateam WP Chat App WordPress plugin affecting all versions up to 3.6.1. It results from improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of user-controlled attributes like 'buttonColor' and 'phoneNumber' in the plugin's widget or block. Authenticated users with contributor or higher privileges can exploit this to inject arbitrary JavaScript that executes in the context of other users viewing the affected pages. The vulnerability has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial impact on confidentiality and integrity with no availability impact. No patch or official fix is currently documented, and no known active exploitation has been reported.

Successful exploitation allows authenticated contributors or higher to inject persistent malicious scripts into pages rendered by the WP Chat App plugin. This can lead to partial confidentiality and integrity compromise of user data within the affected WordPress site context. There is no impact on availability. The vulnerability requires authenticated access with contributor-level permissions or above, limiting the attack surface. No known exploits in the wild have been reported.

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 removing the WP Chat App plugin if possible. Monitor for updates from ninjateam regarding a security patch. Avoid granting contributor or higher permissions to untrusted users to reduce risk.
