CVE-2020-11010: 
Python vulnerability analysis and mitigation

CVE-2020-11010 is a SQL injection vulnerability discovered in the Tortoise ORM Python package affecting versions <0.15.23 and 0.16.0-0.16.5. The vulnerability was disclosed on April 18, 2020, and impacts the package's handling of character/text fields in MySQL, SQLite, and PostgreSQL databases (GitHub Advisory).

The vulnerability exists in the SQL query generation when using filtering operations or performing mass-updates on char/text fields. For MySQL databases, the issue affects general filtering and mass-update operations. For SQLite and PostgreSQL, the vulnerability specifically manifests when using contains, starts_with, ends_with filters and their case-insensitive counterparts. The issue stems from improper escaping of special characters in SQL queries (GitHub Advisory).

If exploited, this vulnerability could allow attackers to perform SQL injection attacks against applications using the affected versions of Tortoise ORM. This could potentially lead to unauthorized database access, data manipulation, or information disclosure (GitHub Advisory).

The vulnerability can be triggered when using character/text field operations in database queries. It affects both regular queries and case-insensitive operations, particularly in filtering and mass-update scenarios (GitHub Advisory).

Users are advised to upgrade to version 0.15.23 or 0.16.6 and above, which contain patches for these SQL injection vulnerabilities. The fix includes proper escaping of special characters and improved handling of SQL query generation (GitHub Advisory).
