Title
Authenticated RCE via Malicious eTemplate Upload in EGroupware
Summary
In egroupware version 26.0 and earlier, an authenticated administrator can achieve OS-level Remote Code Execution (RCE) by uploading a malicious eTemplate XML file (`.xet`) to the VFS `/etemplates` mount. The `Widget::expand_name()` method passes template widget attribute values directly into a PHP `eval()` call with only double-quote escaping applied - **backtick characters are not escaped**. In PHP, backticks inside a double-quoted `eval()` string execute shell commands. This allows an admin-level user to escalate from web application access to arbitrary OS command execution on the server.

Title
Remote Code Execution Vulnerability in EGroupware
Summary
A vulnerability has been identified in EGroupware that may lead to Remote Code Execution (RCE). The issue allows an authenticated attacker to execute arbitrary commands on the server. If user self-registration is enabled, the vulnerability may be exploitable without prior authentication. The vulnerability stems from improper authorization checks combined with a file write primitive and an arbitrary file read vulnerability, which together enable full system compromise. This has been patched in versions 26.2.20260224 and 23.1.20260224.

Title
EGroupware has SQL Injection in Nextmatch Filter Processing
Summary
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.
