Description

EGroupware is a Web based groupware server written in PHP. A SQL Injection vulnerability exists in the core components of EGroupware prior to versions 23.1.20260113 and 26.0.20260113, specifically in the Nextmatch filter processing. The flaw allows authenticated attackers to inject arbitrary SQL commands into the WHERE clause of database queries. This is achieved by exploiting a PHP type juggling issue where JSON decoding converts numeric strings into integers, bypassing the is_int() security check used by the application. Versions 23.1.20260113 and 26.0.20260113 patch the vulnerability.
