CVE-2023-5870
This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.
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.
