Description

This security bulletin contains information about 1 vulnerability.


1) Argument injection (CVE-ID: CVE-2026-105326)

CWE-ID: CWE-88 - Argument Injection or Modification

CVSSv4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to execute arbitrary code with the privileges of the filter user (lp).

The vulnerability exists due to argument injection in the mailto notifier's pipe_sendmail function in notifier/mailto.c when passing subscription recipient addresses to sendmail. A local user can create a printer subscription with a crafted notify-recipient-uri that causes sendmail to load an attacker-controlled configuration file to execute arbitrary code with the privileges of the filter user (lp).

Exploitation requires traditional sendmail with support for the -C option and a subscribed event to trigger notification delivery.
