CVE-2026-111601

13th percentile - higher than 13% of all known CVEs

The Hippoo Mobile App for WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'token_id' parameter in all versions up to, and including, 1.12.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The URL path regex constrains the path segment to word characters, but WP_REST_Request's query-string parameter precedence allows a ?token_id= value to override it and reach the handler verbatim, bypassing the regex constraint entirely.

An attacker can execute arbitrary JavaScript in the victim's browser, potentially leading to session theft, redirections, or other actions in the context of the site.

Update the Hippoo Mobile App for WooCommerce plugin to a version newer than 1.12.0 that fixes this vulnerability. Inform users about the risk of clicking suspicious links.
