Potential fix for https://github.com/GSA/eoc/security/code-scanning/25
To fix this vulnerability, we need to ensure that the value retrieved from the
data-lazyattribute (imageSource) is safe before using it as thesrcattribute of an image. The best way is to validate thatimageSourceis a URL with an allowed protocol (e.g.,http:,https:, or maybedata:), and does not start with dangerous schemes likejavascript:orvbscript:.The change should be applied in the
loadImagesfunction, specifically before settingimageToLoad.srcand/orimage.attr('src', imageSource). If the value is invalid, we should skip loading the image and mark it as an error.To implement this, we need a helper function to validate image URLs. We can define a simple validator within the same file, above the
loadImagesfunction.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
