What it is

phpMyFAQ before 4.1.9 contains an SQL injection vulnerability in PdoMysql::escape(), which escapes single quotes with backslashes that are treated literally when MySQL or MariaDB runs in NO_BACKSLASH_ESCAPES mode. Unauthenticated attackers can send a Unicode right single quotation mark in the search parameter of api/autocomplete, which is normalized to an ASCII quote, to read credentials and configuration secrets, modify records, or drop tables.
