Summary
SQL Injection vulnerability in NextGEN Gallery prior to version 4.2.1. An authenticated attacker with 'NextGEN Gallery overview' capability can inject arbitrary SQL into the ORDER BY clause via the 'orderby' parameter in REST API endpoints.

Original NVD description (English source)
NextGEN Gallery version prior to 4.2.1 are vulnerable to authenticated SQL injection via the 'orderby' parameter on the REST API endpoints '/imagely/v1/galleries' and '/imagely/v1/albums'. The root cause is an insufficient sanitization function ('_clean_column()') in the data mapper layer that uses a character blacklist instead of a whitelist approach. This allows an authenticated attacker with the 'NextGEN Gallery overview' capability (assigned to the Administrator role by default) to inject arbitrary SQL into the 'ORDER BY' clause.
