MEDIUM 4.4EPSS 2.56%

Does this matter?

Lower severity and a low EPSS score (2.56%). Track it; it rarely justifies an emergency change on its own.

Description

A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.
