Foresight · where to check next

No weakness class or product neighbourhood is held for this record, so this index cannot name anywhere to check next. That is an absence in the record, not a finding about the software.

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 User Registration & Membership WordPress plugin before 4.1.2 does not prevent users to set their account role when the Membership Addon is enabled, leading to a privilege escalation issue and allowing unauthenticated users to gain admin privileges receipt
