What is CVE-2024-36039?

A security vulnerability in PyMySQL versions up to 1.1.0 exposes applications to SQL injection attacks when untrusted JSON input is utilized. This occurs because the keys within the input are not properly escaped by the escape_dict function, potentially allowing malicious users to manipulate SQL queries. Developers are urged to upgrade to version 1.1.1 or later and thoroughly sanitize all JSON inputs to safeguard against this type of attack.
