CVE-2026-86798 Details
Description
The HootBoard WordPress plugin through 3.1.4 does not perform any authorisation check on some of its REST endpoints, and does not escape the values stored through them before outputting them in a public page, allowing unauthenticated users to inject arbitrary web scripts that will execute in the browser of anyone visiting that page, including administrators.
A stored cross-site scripting vulnerability has been identified in the HootBoard WordPress plugin, affecting versions through 3.1.4. The issue arises because the plugin's REST endpoints lack proper authorization checks and fail to sanitize values before displaying them on public pages. This oversight allows unauthenticated users to inject arbitrary scripts that execute in the browsers of visitors to that page, including administrators.
