PostgreSQL is vulnerable to Denial Of Service (DOS). The vulnerability is caused due to a flaw involving pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. This can lead to a remote high privileged user to launch a denial of service (DoS) attack.
