The manipulation of the argument category_names/catOrderIds/image-ordering with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89.

As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Joomla Extension - OrdaSoft.com - Authenticated, Privileged SQL Injection in OrdaSoft Joomla Gallery extension for Joomla < 6.2.7 - The extensions saveGallery() passes form data through a hand-rolled parser into Joomla’s Input object, then reads it back with the ARRAY/ STRING filter types, neither of which sanitises SQL content. Values from category_names[], catOrderIds, and image-ordering fields were concatenated directly into SQL with no quoting or integer cast, giving an authenticated core.manage user (a permission scoped to managing one gallery component, not administrator-wide trust) full read/write access to the database, including UNION-based extraction of #__users password hashes.
