Casengo Live Chat Support versions up to 2.1.4 contain a CSRF vulnerability that enables stored XSS attacks via the chat widget. The vulnerability allows an attacker to trick authenticated users into executing unwanted actions, which can result in persistent malicious scripts being stored and executed in the context of the application. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability.

Successful exploitation could allow attackers to execute stored cross-site scripting attacks, potentially compromising user sessions, stealing sensitive information, or disrupting service availability. The vulnerability affects confidentiality, integrity, and availability of the affected system. However, no known exploits are currently reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider implementing CSRF protections such as anti-CSRF tokens and input validation to mitigate risk. Monitor vendor communications for updates on patches or official mitigations.
