Zope before 2.2.4 allows partially trusted users to bypass security controls for certain methods by accessing the methods through the fmt attribute of dtml-var tags.

Zope 2.2.0 through 2.2.4 does not properly perform security registration for legacy names of object constructors such as DTML method objects, which could allow attackers to perform unauthorized activities.

docutils in Zope 2.6, 2.7 before 2.7.8, and 2.8 before 2.8.2 allows remote attackers to include arbitrary files via include directives in RestructuredText functionality.

Zope before 2.2.4 allows partially trusted users to bypass security controls for certain methods by accessing the methods through the fmt attribute of dtml-var tags.
