Vulnerability Title
Frappe: Missing authorization in toggle_like and mark_as_seen
Source: CVE Program / CVE List V5
Vulnerability Description
Frappe is a full-stack web application framework. In version 16.31.0 and earlier, the whitelisted toggle_like and mark_as_seen endpoints in frappe/desk/like.py and frappe/desk/doctype/note/note.py do not enforce read permission before modifying _liked_by metadata or a Note seen state. An authenticated user can interact with documents or notes that the user cannot read, disclosing resource existence and modifying resource-associated metadata. No released fixed version is available as of this review.
