PMB 7.4.6 contains a SQL injection vulnerability in the id parameter of the storage module (categ=storage) of the opac_css/ajax.php endpoint that allows remote attackers to manipulate database queries. Attackers can exploit the unsanitized 'id' parameter by injecting conditional sleep statements to extract information or perform time-based blind SQL injection attacks.
