What is CVE-2026-86794?

The Community Events WordPress plugin is susceptible to arbitrary web script injection due to inadequate authorization and nonce checks when handling public event submissions. This vulnerability allows unauthenticated users to inject and execute malicious scripts in the browser of administrators reviewing event submissions. Furthermore, the plugin fails to properly escape several submitted values before outputting them in the administration dashboard and on the public calendar, heightening the risk of exploitation.

Affected Version(s)

Community Events 1.4.9 < 1.6.0

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.
