CVE-2024-21272Public exploitNetwork attack vector

SQL injection via recursive dictionary parameter substitution

Published Oct 15, 2024 · Updated Oct 16, 2024

SQL injection in Oracle MySQL Connector/Python 9.0.0 and earlier allows remote authenticated users to take over connector operations. In the C-extension cursor.execute() path, dictionary-based substitution repeatedly replaces placeholder text, so a value containing another placeholder becomes query syntax. Exploitation requires low-privileged MySQL protocol access and attacker-controlled dictionary parameters, enabling unauthorized reads, writes, and service interruption under the connector's database privileges.
