What is CVE-2026-89300?
The WP Verify API plugin for WordPress, up to version 1.0.0, is susceptible to a serious authorization bypass vulnerability. This flaw allows unauthenticated users to access specific REST API routes, which lack proper security checks. As a result, malicious actors can insert arbitrary data directly into the plugin's database and initiate the sending of templated verification emails to any email address. Additionally, there are no rate limiting measures in place, exacerbating the potential for abuse.
Affected Version(s)
WP Verify API 0 <= 1.0.0
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
