CVE-2026-27823
A vulnerability has been identified in EGroupware that may lead to Remote Code Execution (RCE).
Overview
CVE-2026-27823 is a known-severity vulnerability. It was published on July 20, 2026.
Technical description
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.
