CVE-2022-46857 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the SiteAlert (Formerly WP Health) WordPress plugin, affecting versions <= 1.9.7. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview
The SiteAlert (Formerly WP Health) plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.9.7. This is due to missing or incorrect nonce validation on one of its functions. This makes it possible for unauthenticated attackers to invoke this function via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in SiteAlert (Formerly WP Health) <= 1.9.7 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For SiteAlert (Formerly WP Health) the fix is 1.9.8: builds <= 1.9.7 are affected, anything from 1.9.8 onward is not.
Remediation
Update to version 1.9.8, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to SiteAlert (Formerly WP Health): WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: SiteAlert (Formerly WP Health) 1.9.8 closes this, and updating the plugin is the step that ends it.
