## Technical details

This is a broken access control vulnerability (CWE-284) in the schema generation feature of the plugin. The vulnerability exists because the plugin does not verify that the user requesting schema generation has permission to edit the specific post being targeted. A contributor or higher-privileged user can exploit this by requesting schema generation for posts authored by others, allowing them to read restricted content including draft, pending, private, and password-protected posts. The issue affects versions 1.63 through 1.65, and has been patched in version 1.66.
