Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the set_title_description subscriber function in src/plone/app/contenttypes/subscribers.py, which sets an object's title directly from a file's filename without enforcing any length limit. An authenticated attacker can upload a file with an arbitrarily long filename, causing the title field to be populated with an unbounded string and resulting in excessive resource consumption or a crash.
