8.6CVE-2026-40187egroupwareegroupware
EPSS score
0.86%
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.
8.7CVE-2026-27823egroupwareegroupware
EPSS score
0.97%
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.
8.8CVE-2026-22243egroupwareegroupware
EPSS score
0.42%
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.

EPSS score
0.35%
An issue was discovered in eGroupWare 17.1.20190111. A User Enumeration vulnerability exists under calendar/freebusy.php, which allows unauthenticated remote attackers to enumerate the users of web applications based on server response.
4.9CVE-2023-38328egroupwareegroupware
EPSS score
0.58%
An issue was discovered in eGroupWare 17.1.20190111. An Improper Password Storage vulnerability affects the setup panel of under setup/manageheader.php, which allows authenticated remote attackers with administrator credentials to read a cleartext database password.
6.1CVE-2023-38329egroupwareegroupware
EPSS score
0.28%
An issue was discovered in eGroupWare 17.1.20190111. A cross-site scripting Reflected (XSS) vulnerability exists in calendar/freebusy.php, which allows unauthenticated remote attackers to inject arbitrary web script or HTML into the "user" HTTP/GET parameter, which reflects its input without sanitization.
