## What is CVE-2026-101110?

CVE-2026-101110 is a critical SQL injection vulnerability in ordasoft.com Book Library (Free) extension for Joomla, published on 28 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Book Library (Free) < 6.4.6 - site/booklibrary.php’s books() function reads the field and direction request parameters and passes each through a function called protectInjectionWithoutQuote(), whose only real protection is a keyword blacklist that, on detecting the literal substring select, wraps the value in $db->quote() instead of rejecting it. The value is then concatenated directly into an unquoted ORDER BY clause, a position where quoting provides no protection at all. Reaching the vulnerable code path requires two conditions: a first request to prime session-stored sort defaults, and a trailing decoy comment (-- xselect) that satisfies the blacklist’s substring check without altering the payload’s effect.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)
