Schema & Structured Data for WP & AMP < 1.60 - Unauthenticated Arbitrary Media Upload

The Schema & Structured Data for WP & AMP WordPress plugin before 1.60 does not check user capabilities on its frontend AJAX file-upload handlers and does not validate the actual content of uploaded files against the endpoint's intended media type, allowing unauthenticated users to upload any file type accepted by WordPress's media library through endpoints that should only accept images or videos.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
