Code Findings

Function constructor used — dynamic code executionMedium

The extension uses the function constructor to execute dynamic code, which can potentially lead to security vulnerabilities.

Technical: The extension uses the function constructor to create new functions dynamically, which can be used for malicious purposes like code injection or privilege escalation.

💡 This pattern is commonly used in legitimate extensions for tasks like code generation or dynamic configuration.

innerHTML assignment — potential XSS vectorMedium

Technical: The extension uses the innerHTML property to assign user-input data to an element, which can be used for malicious purposes like XSS attacks.

💡 This pattern is commonly used in legitimate extensions for tasks like content rendering or dynamic UI updates.

String.fromCharCode (obfuscation)Medium

The extension uses String.fromCharCode to obfuscate code, which can make it harder to analyze and understand the extension's behavior.

Technical: The extension uses String.fromCharCode to convert character codes to strings, which can be used for malicious purposes like code obfuscation or anti-debugging techniques.

💡 This pattern is commonly used in legitimate extensions for tasks like data encoding or formatting.

Captures keystrokesCritical

The extension captures keystrokes, which can potentially lead to security vulnerabilities and unauthorized access to sensitive information.

Technical: The extension uses the keyboard API to capture keystrokes, which can be used for malicious purposes like keylogging or password harvesting.

💡 This pattern is not commonly used in legitimate extensions due to its potential for abuse.

Bottom Line

The WPS PDF Read Edit Fill Co extension poses a moderate risk to users due to its access to sensitive data and potential for security vulnerabilities. While it provides useful features for managing PDFs, users should exercise caution when installing and using this extension.
