If the "enable-acl" cluster option isn't enabled, members of the "haclient" group can modify Pacemaker's Cluster Information Base without restriction, which already gives them these capabilities, so there is no additional exposure in such a setup. For the stable distribution (buster), this problem has been fixed in version 2.0.1-5+deb10u1. We recommend that you upgrade your pacemaker packages.
