TIMELINE Aug 4 Reserved by WPScan Aug 10 Published (CNA: WPScan) Aug 11 EXPLOIT PUBLISHED — CVE-2026-18786 (Unknown CheckView). Public exploit reference added.
The CheckView WordPress plugin before 2.3.2 does not restrict its REST API authentication filter to its own routes and unconditionally discards the authentication error raised for any request whose URI merely contains a CheckView WordPress plugin before 2.3.2-specific string, making it possible for unauthenticated attackers to bypass the REST nonce check and perform any REST action available to a logged-in administrator, such as creating a new administrator account, via a crafted link an administrator is tricked into opening.
