  - In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when using Postgres
    database extension, supplying invalid parameters to the parametrized query may lead to PHP attempting to
    free memory using uninitialized data as pointers. This could lead to RCE vulnerability or denial of
    service. (CVE-2022-31625)
