Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to leveraging missing schema qualifiers on privileged functions called by the aiven-extras extension. A low privileged user can acquire `superuser` privileges, which would allow full, unrestricted access to all data and database functions and could lead to arbitrary code execution or data access on the underlying host as the `postgres` user.

Mitigation
Install updates from vendor's website.
