dalfox

Dalfox is an advanced XSS scanning and parameter analysis tool designed for integration into automated security workflows within Canva. It efficiently identifies cross-site scripting vulnerabilities in web applications, providing critical insights for developers and security teams.

Ideal Use Cases & Fit​

Dalfox excels in scenarios where automated vulnerability scanning is necessary, particularly during continuous integration and deployment phases. It is best suited for environments requiring rapid identification of XSS flaws across multiple endpoints. The tool is particularly effective when processing a list of target URLs, enabling rapid assessment of web applications. However, it may not be suitable for highly complex web applications with extensive and dynamic JavaScript, where a more manual or specialized approach might be necessary.

Value in Workflows​

Integrating Dalfox into security workflows enhances early reconnaissance and vulnerability management stages. By automating the detection of XSS vulnerabilities, Dalfox facilitates efficient monitoring and validation of security measures throughout the development lifecycle. This streamlining of processes helps teams maintain code integrity and enhances overall security posture.

Input Data​

Dalfox accepts newline-separated URLs as input, which are specified in a file format. The function of this input is to serve as the target for scanning. An example input might include:

https://example.com/page1
https://example.com/page2

Configuration​

  • target: Specifies the input file containing URLs to be scanned (required).
  • format: Controls the output format (default is JSON, required).
  • timeout: Sets the timeout duration for requests (default is 10 seconds).
  • proxy: Configures a proxy server for routing requests (required).
  • waf-evasion: Adjusts speed to avoid web application firewalls (default is false).
  • silence: Controls verbosity, limiting output to PoC code and progress (required).
  • output-all: Decides whether to write all logs to output (default is false).
  • method: Allows overriding of HTTP methods used (default is GET).
  • user-agent: Enables the addition of a custom user-agent string.
  • cookie: Permits the inclusion of custom cookies in requests.

This configuration allows workflow designers to customize Dalfox's scanning behavior and integration based on specific security requirements. Updated: 2026-02-10
