Echo: cups: security update to 2.4.18-1+e4

low Tenable Cloud Security Plugin ID 474850

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- An argument injection flaw was found in CUPS. When email notification is configured, the CUPS scheduler
accepts printer subscription requests that supply a mailto notify-recipient-uri. The mailto notifier
passes the recipient address to the configured sendmail program without ensuring it cannot be interpreted
as command-line options. A remote attacker who can reach the CUPS service could supply a crafted recipient
value starting with "-" to influence sendmail behavior. Successful exploitation depends on the installed
mail transfer agent and CUPS network exposure, and may lead to execution of attacker-controlled commands
with the privileges of the CUPS service user. (CVE-2026-105326)

Solution

Update the cups library and its related packages to version 2.4.18-1+e4 or later.
