Authenticated SQL injection via imported meta key
Published Aug 6, 2026 · Updated Aug 6, 2026
SQL injection in Welcart e-Commerce before 2.11.32 allows remote authenticated users to read database data through a crafted CSV import. The custom_field parser accepts an attacker-controlled meta key after the ;; separator and inserts it into a postmeta DELETE statement whose prepared output is passed through stripslashes(), allowing SQL syntax to escape the quoted key list. Editor, wc_management, or wc_author access to the Master Items import is required; the demonstrated time-based oracle supports blind extraction of data such as WordPress password hashes.
