CVE-2026-86794 Details
Description
The Community Events WordPress plugin before 1.6.0 does not have authorisation or nonce checks when processing public event submissions, and does not escape several of the submitted values before outputting them in the administration dashboard and on the public calendar, allowing unauthenticated users to inject arbitrary web scripts that will execute in the browser of an administrator reviewing the submission.
A stored cross-site scripting vulnerability has been identified in the Community Events WordPress plugin, affecting versions prior to 1.6.0. The issue arises because the plugin does not implement proper authorization or nonce checks for public event submissions. Additionally, several submitted values are not adequately escaped before being displayed in the administration dashboard and on the public calendar. This oversight allows unauthenticated users to inject arbitrary web scripts that execute in the browser of an administrator reviewing the submission.
Users are advised to update the Community Events WordPress plugin to version 1.6.0 or later.
