This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires an initial comment approval, though WordPress default settings will auto-approve all subsequent comments from the same author, allowing a patient unauthenticated attacker to land the payload without further admin intervention. ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
