Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-8747-1 advisory.

 It was discovered that Beets incorrectly escaped untrusted media metadata in its web interface. An attacker could possibly use this issue to inject arbitrary HTML or execute arbitrary JavaScript code in a user's browser.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
