Detailsinfo

A vulnerability, which was classified as critical, was found in egroupware. Affected is the function is_int of the component Nextmatch Filter Handler. The manipulation with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89.

This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-22243 since 01/07/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1505.

Upgrading to version 23.1.20260113 or 26.0.20260113 eliminates this vulnerability.
