    Package        : python-pymysql
    Version        : 0.9.3-1+deb10u1
    CVE ID         : CVE-2024-36039
    Debian Bug     : 1071628

    It was discovered that there was a potential SQL injection attack
    in python-pymysql, a MySQL client library for Python. This was
    exploitable when python-pymysql was used with untrusted JSON input
    as keys were not escaped by the escape_dict routine.

    For Debian 10 buster, this problem has been fixed in version
    0.9.3-1+deb10u1.

    We recommend that you upgrade your python-pymysql packages.

    For the detailed security status of python-pymysql please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/python-pymysql
