Fixed in3.4.1receipt

A rung lights from a row in the index, never from an assessment. "Held sources" is the true scope of the claim: this index reads the CVE record, NVD, CISA KEV, FIRST's EPSS and public proof-of-concept repositories, and it does not observe attacks.

Did this affect your environment?Answering needs an account.

What it is stated by the CNA

The Masteriyo LMS WordPress plugin before 3.4.1 does not verify ownership of, or restrict the type of, the records a user requests for download, allowing users with the instructor role to retrieve the full content and metadata of arbitrary posts, including other instructors' private and draft courses. receipt
