CVE-2021-24630Public exploitNetwork attack vector

Authenticated SQL injection via interpolated GET parameters

Published Nov 8, 2021 · Updated Aug 3, 2024

SQL injection in Schreikasten 0.14.18 and earlier allows remote authenticated users with Author access to read database data. Comments-dashboard edit, tracking, spam, ham, and blacklist handlers insert the id or tid GET value directly into SQL query strings without validation, escaping, or parameterization. An Author account and access to wp-admin are required; demonstrated time-delay payloads provide a database oracle, while broader write or command-execution impact is not established.
