Unvalidated dynamic method call High

Invocation of method with
user-controlled
name may dispatch to unexpected target and cause an exception.

Copilot Autofix AI 10 days ago

To fix the problem, we need to ensure that the callId is validated before using it to access the pendingCalls object. This can be achieved by checking if callId is a property of pendingCalls and if the corresponding value is a function before invoking it. This approach prevents unauthorized access and ensures that only valid methods are called.

Client-side cross-site scripting High

Cross-site scripting vulnerability due to
user-provided value
.

Copilot Autofix AI 10 days ago

To fix the problem, we need to ensure that the input data is properly sanitized before being processed by the marked function. The best way to do this is to use a library that can sanitize HTML content, such as DOMPurify. This library will help us remove any potentially harmful scripts from the input.

  1. Import the DOMPurify library.
  2. Use DOMPurify to sanitize the data.notes before passing it to the marked function.

Client-side URL redirect Medium

Untrusted URL redirection depends on a
user-provided value
.

Copilot Autofix AI 10 days ago

To fix the problem, we need to ensure that the URL used for redirection is validated against a list of authorized URLs. This can be achieved by maintaining a list of trusted URLs and checking if data.url is in this list before constructing the currentURL and upcomingURL. If data.url is not in the list, we should not proceed with the redirection.

  1. Create a list of authorized URLs.
  2. Check if data.url is in the list of authorized URLs before using it to construct currentURL and upcomingURL.
  3. If data.url is not authorized, handle the situation appropriately (e.g., log an error, use a default URL, etc.).

To fix the problem, we need to ensure that the data.url is properly sanitized before being used to construct the upcomingURL. This can be achieved by using a library like DOMPurify to sanitize the URL or by validating the URL to ensure it conforms to expected patterns.

  • Import the DOMPurify library to sanitize the URL.

  • Update the relevant lines in the setupIframes function to include the sanitization step.

DOM text reinterpreted as HTML Medium

DOM text
is reinterpreted as HTML without escaping meta-characters.

Copilot Autofix AI 10 days ago

To fix the problem, we need to ensure that the href attribute value is properly sanitized before it is used to construct the URL for the stylesheet. One way to do this is to use a function that escapes any potentially dangerous characters in the href value. This will prevent any malicious content from being interpreted as HTML or JavaScript.

We will create a utility function to escape the href value and use it in the getRevealJsPath function. This function will replace any potentially dangerous characters with their corresponding HTML entities.
