    Title
    Simple Ajax Chat <= 20231101 - Authenticated (Admin+) Stored Cross-Site Scripting
    Summary
    The Simple Ajax Chat – Add a Fast, Secure Chat Box plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 20231101 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

    CVE-2024-2956 (GCVE-0-2024-2956)

    Vulnerability from cvelistv5 – Published: 2024-03-27 07:34 – Updated: 2026-04-08 17:11

    Title
    Simple Ajax Chat <= 20231101 - Authenticated (Admin+) Stored Cross-Site Scripting
    Summary
    The Simple Ajax Chat – Add a Fast, Secure Chat Box plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 20231101 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
