Attack-Flow Graph

Executive Summary

The Ivory Search WordPress plugin is vulnerable to Stored Cross-Site Scripting (XSS) through its 'menu_title' and 'menu_magnifier_color' settings. This vulnerability exists in all versions up to and including 5.5.15 because the plugin does not properly sanitize input or escape output. As a result, an authenticated attacker with administrator-level access or higher can inject malicious scripts that execute whenever a user views the affected page.

Impact Analysis

This vulnerability allows attackers with administrator privileges to inject arbitrary web scripts into pages. These scripts execute when users access the injected pages, potentially leading to unauthorized actions such as stealing user credentials, hijacking user sessions, or performing actions on behalf of users without their consent.

Compliance Impact

The vulnerability allows authenticated attackers with administrator-level access to inject arbitrary web scripts via stored cross-site scripting (XSS). This could lead to unauthorized access or manipulation of sensitive data, potentially impacting confidentiality and integrity.

Such security weaknesses may affect compliance with standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive data against unauthorized access and attacks.

However, the provided information does not explicitly describe the direct impact on compliance with these standards.
