CVE-2026-18786CheckView < 2.3.2 - Administrator Account Creation via REST API Authentication Bypass
High 8.8
In plain English
A high-severity improper authentication in CheckView from Unknown. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.5% (higher than 46% of all known vulnerabilities).
Official description
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.
