Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
KEDA versions before 2.20.0 are affected by a connection string injection in the PostgreSQL scaler, where tenant-supplied host, port, userName, dbName and sslmode values are escaped only for spaces and not for other whitespace or backslashes. An attacker who can create a TriggerAuthentication or ScaledObject could inject extra connection parameters, such as forcing sslmode=disable or redirecting the host to capture the operator's password. Upgrade to KEDA 2.20.0 or later; the source lists no other workaround.
