EGroupware has SQL Injection in Nextmatch Filter Processing

Published Jan 28, 2026 · Updated Jan 28, 2026 · Assigned by GitHub_M

Vendor: EGroupware Product: egroupware Package: egroupware/egroupware Ecosystem: Packagist

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.
