plone.app.dexterity is a content-type system for the Plone content management system, and plone.app.contenttypes provides Plone’s Dexterity-based content types. Plone.app.dexterity versions through 3.2.2, 4.0.0 through 4.1.2, and 5.0.0, and plone.app.contenttypes versions through 3.0.11, 4.0.0 through 4.0.9, and 5.0.0 are vulnerable to denial of service because an authenticated user can create content with excessively long titles, descriptions, or uploaded-file names, causing Plone to become unresponsive and potentially making the resulting content difficult to edit or delete. The vulnerability is patched in plone.app.dexterity versions 3.2.3, 4.1.3, and 5.0.1, and in plone.app.contenttypes versions 3.0.12, 4.0.10, and 5.0.1.
