MoinMoin 1.7.x before 1.7.3 and 1.8.x before 1.8.3 checks parent ACLs in certain inappropriate circumstances during processing of hierarchical ACLs, which allows remote attackers to bypass intended access restrictions by requesting an item, a different vulnerability than CVE-2008-6603.

MoinMoin 1.6.2 and 1.7 does not properly enforce ACL checks when acl_hierarchic is set to True, which might allow remote attackers to bypass intended access restrictions, a different vulnerability than CVE-2008-1937.
