Name of the Vulnerable Software and Affected Versions WP Allowed Hosts plugin for WordPress versions up to and including 1.0.8

Description The WP Allowed Hosts plugin for WordPress is susceptible to Stored Cross-Site Scripting through the allowed-hosts parameter. Insufficient input sanitization and output escaping allow authenticated attackers with administrator-level access or higher to inject arbitrary web scripts into pages. These scripts execute when a user accesses the injected page. This issue specifically impacts multi-site installations and those where unfiltered html has been disabled.

Recommendations Update the WP Allowed Hosts plugin to a version later than 1.0.8.
