Summary

plone.app.contenttypes has a Denial of Service in File Upload due to excessive filename length

Details

Impact

When creating an Image or File with a very large filename, Plone can become unresponsive. Even if the content loads, it can be hard to edit or delete, because the UI is unwieldy.

On Plone 6.2, upgrade to plone.app.contenttypes 5.0.1.
On Plone 6.1, upgrade to plone.app.contenttypes 4.0.10.
On Plone 6.0, upgrade to plone.app.contenttypes 3.0.12

Another part of this problem has been patched in plone.app.dexterity. See this advisory.

Workarounds
