CVE-2023-0553: Thingsforrestaurants Quick Restaurant Menu

Medium severity, CVSS 4.4. EPSS: 0.5% chance of exploitation in the next 30 days.

The Quick Restaurant Menu plugin for WordPress is vulnerable to Stored Cross-Site Scripting via its settings parameters in versions up to, and including, 2.0.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Affected products

• Thingsforrestaurants Quick Restaurant Menu: before 2.1.0 (fixed in 2.1.0)
