CVE-2026-22243
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
