To fix this issue, we need to ensure that the file being used as the source for the image is safe and does not contain any malicious content. One way to achieve this is by validating the file type and size before using it. Additionally, we can use a library like DOMPurify to sanitize any potentially unsafe content.
- Validate the file type and size before setting it as the
selectedSegmentImage. - Use DOMPurify to sanitize the URL if necessary.

To fix this issue, we need to ensure that the selectedSegmentImage is properly sanitized before being used as the src attribute of an Image object. One way to achieve this is by validating the file type and ensuring it is a legitimate image file. Additionally, we can use a safer method to handle the image URL.
- Validate the file type to ensure it is an image.
- Use
URL.createObjectURLto create a safe URL for the image file. - Ensure that the
selectedSegmentImageis only set if the file type is valid.
