What is CVE-2026-84741?

The Events Calendar plugin for WordPress, prior to version 6.17.5, exhibits a serious flaw in its handling of linked records. Specifically, the plugin fails to verify the post status of these records before including their details in responses from the public REST API. This oversight enables unauthenticated users to access and read the information of records that have not been published, thereby exposing sensitive data. It is critical for users to update to the latest version to mitigate potential data breaches.

Affected Version(s)

The Events Calendar 4.5 < 6.17.5

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.
