Code Findings

Document.write() used — injection riskMedium

The extension uses document.write(), which can inject malicious code into web pages. This poses a risk to users who visit compromised websites.

Technical: The extension's JavaScript files use document.write() to inject content into web pages. This can be exploited by attackers to inject malicious scripts or steal user data.

💡 Legitimate extensions may use document.write() for legitimate purposes such as injecting SEO-related data or analytics code.

innerHTML assignment — potential XSS vectorMedium

The extension assigns innerHTML, which can be exploited by attackers to inject malicious scripts or steal user data.

Technical: The extension's JavaScript files assign innerHTML to HTML elements, creating a potential cross-site scripting (XSS) vector. Attackers can exploit this vulnerability to inject malicious code into web pages.

💡 Legitimate extensions may use innerHTML assignment for legitimate purposes such as injecting SEO-related data or analytics code.

Writes to clipboardMedium

The extension writes data to the user's clipboard, which can be a security risk if sensitive information is stored there.

Technical: The extension uses the navigator.clipboard API to write data to the user's clipboard. This poses a risk if sensitive information is stored in the clipboard.

💡 Legitimate extensions may use the clipboard for legitimate purposes such as copying SEO-related data or analytics code.

Bottom Line

SEOquake has some security concerns due to excessive permissions and potential vulnerabilities. While it offers useful features, users should exercise caution when installing and using this extension. We recommend reviewing the extension's permissions and behavior before installation.
