CVE-2026-85129: Unknown Hoo Companion

High severity, CVSS 8.8. EPSS: 0.5% chance of exploitation in the next 30 days.

The Hoo Companion WordPress plugin 1.0.2 does not have any authorisation or validation checks in one of its import features, and does not sanitise the data submitted to it before storing it as the active theme's settings, allowing unauthenticated attackers to inject arbitrary web scripts which will execute for anyone viewing the site, including administrators. The same request destroys the site's existing theme settings.

Affected products

• Unknown Hoo Companion: from 1.0.2, up to and including 1.0.2
