Code Findings
Dynamic Code ExecutionHigh
The extension uses the Function constructor to execute dynamic code, which can be a security risk if not properly sanitized.
Technical: The extension uses Function to create new functions dynamically, which can lead to code injection attacks if malicious code is injected into the function body.
💡 Legitimate extensions may use dynamic code execution for legitimate purposes such as content injection or script loading.
Potential XSS VectorMedium
The extension uses innerHTML assignment, which can be a potential XSS vector if not properly sanitized.
Technical: The extension assigns innerHTML to an element without proper sanitization, which can lead to cross-site scripting attacks if malicious code is injected into the HTML.
💡 Legitimate extensions may use innerHTML assignment for legitimate purposes such as content injection or script loading.
ObfuscationMedium
The extension uses String.fromCharCode and charCodeAt to obfuscate code, which can make it harder to analyze and debug.
Technical: The extension uses these functions to encode and decode strings, making it difficult to understand the intent behind the code.
💡 Legitimate extensions may use obfuscation for legitimate purposes such as protecting intellectual property or preventing reverse engineering.
Broad Host PermissionsCritical
The extension has broad host permissions, which can be a security risk if not properly managed.
Technical: The extension has access to all URLs visited in the browser, which can lead to unauthorized data exposure or manipulation.
💡 Legitimate extensions may require broad host permissions for legitimate purposes such as content injection or script loading.
Bottom Line
Malwarebytes Browser Guard is a complex extension that provides robust protection against online threats. However, its broad host permissions and dynamic code execution raise some security concerns. Users should carefully review the extension's permissions and behavior before installing it.
