What we check for

CriticalCVE-2026-1011102026-09-28

Book Library (com_booklibrary) below 6.4.6 - Unauthenticated SQL Injection

Book Library by OrdaSoft before 6.4.6 passes the field and direction request parameters of its public book listing through protectInjectionWithoutQuote(), a keyword blacklist that quotes rather than rejects a suspicious value, and then concatenates the result into an unquoted ORDER BY clause where quoting gives no protection. No login is needed. CVE-2026-101110, CVSS 4.0 9.3 Critical. The CVE record names the Free edition; the Pro and ShopPro editions share the element and version numbering. The record title gives the fix as 6.4.6 while its affected range runs to 6.4.6; update to the newest release OrdaSoft offers. If you cannot update, disable the component until you can.

Affected versions: < 6.4.6

Book Library (com_booklibrary) below 6.4.6 - Reflected Cross-Site Scripting

Book Library by OrdaSoft before 6.4.6 echoes the raw title request parameter into a double-quoted HTML attribute on the public book page (site/views/view_book/tmpl/default.php) with no escaping, so a crafted link runs script in the browser of whoever opens it. CVE-2026-101111, CVSS 4.0 5.3 Medium. Update to the newest release OrdaSoft offers.

Affected versions: < 6.4.6
