How the CVE Works
The Ultimate Auction Pro plugin (≤ v1.5.2) for WordPress fails to sanitize the `auction_id` parameter in SQL queries, enabling unauthenticated attackers to inject malicious SQL payloads. The lack of prepared statements allows arbitrary query execution, exposing sensitive database content like user credentials or auction data. Attackers craft requests with manipulated `auction_id` values (e.g., 1; DROP TABLE users--), bypassing input validation and directly altering query logic. This flaw stems from insecure dynamic query construction using unsanitized user input.
