A notable security flaw, identified as CVE-2022-4656, has been discovered in the WP Visitor Statistics (Real Time Traffic) WordPress plugin. This vulnerability could allow an attacker to inject malicious code into websites, potentially harming visitors or stealing sensitive information.
The issue stems from insufficient validation and sanitization of a shortcode attribute within the plugin. This oversight creates an opening for malicious actors, even those with relatively low-level access (like a contributor role), to perform a Stored Cross-Site Scripting (XSS) attack. In simpler terms, an attacker could save harmful scripts directly onto your website, which would then execute whenever an unsuspecting user views the affected content.
