Routine

MEDIUM 6.1UPGRADE

CVE-2026-101111 is a medium-severity flaw (CVSS 6.1) affecting book library. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Joomla Extension - ordasoft.com - Reflected Cross-Site Scripting in Book Library (Free) < 6.4.6 - The public book-detail page template, site/views/view_book/tmpl/default.php, echoes the raw title request parameter directly into a double-quoted HTML attribute with no escaping function of any kind (echo $_REQUEST["title"];). A value containing a double quote closes the attribute early and allows arbitrary HTML/JavaScript to follow.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
