Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Umbraco.Cms versions 14.0.0 up to but not including 14.1.2 are affected. A few Management API endpoints were not protected by a specific section permission and only required authentication, so an authenticated member account could use its token to retrieve information from them. Upgrade to Umbraco.Cms 14.1.2 or later. The source gives few details on which endpoints were affected.
