What is CVE-2022-2625?

CVE-2022-2625 is a high-severity vulnerability in Fedoraproject Fedora, published on 18 Aug 2022. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

Official description

A vulnerability was found in PostgreSQL. This attack requires permission to create non-temporary objects in at least one schema, the ability to lure or wait for an administrator to create or update an affected extension in that schema, and the ability to lure or wait for a victim to use the object targeted in CREATE OR REPLACE or CREATE IF NOT EXISTS. Given all three prerequisites, this flaw allows an attacker to run arbitrary code as the victim role, which may be a superuser.

Weakness: CWE-1321, CWE-915
