Description

This security bulletin contains information about 1 vulnerability.


1) Eval Injection (CVE-ID: CVE-2026-63011)

CWE-ID: CWE-95 - Eval Injection

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows an authenticated remote attacker to execute arbitrary operating system commands as the web server user in GroupOffice.

The vulnerability exists due to insufficient validation of attacker-controlled templates in TemplateParser when the Contact/labels endpoint processes assignment expressions containing variable references. An authenticated remote attacker can submit a crafted template and an existing contact ID in a single request to execute commands without elevated privileges or victim interaction.
