CVE-2026-101110

CriticalCVSS 9.3
Published: Translated: NVD NIST

Summary

Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Book Library (Free) < 6.4.6. The books() function in site/booklibrary.php 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.

Risk Assessment

The risk includes unauthorized access to the database, which could lead to data leakage or modification.

Recommendation

Update the Book Library extension to version 6.4.6 or later if a patch is available, and restrict access to the frontend.
