CVE-2009-4762: MoinMoin Improper Access Control vulnerability

May 2, 2022 (updated October 1, 2024)

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.
