When processing Pixeldrain URLs, cyberdrop-dl-patched could send an Authorization header that includes the user's API key to unverified hosts.
// detailsPixeldrain offers several alternative domains in case the user's ISP blocks the primary domain. To support this, requests made by cyberdrop-dl-patched are not hardcoded and will use the same host as the input URL for API requests.
cyberdrop-dl-patched matches URLs to a crawler based on their host. If the host contains a crawler's supported host as a sub-string, it will match to that crawler.
An URL from a malicious domain (ex: https://evil-pixeldrain.com) would successfully match to the Pixeldrain crawler and cyberdrop-dl-patched will blindly use that host for any API request (https://evil-pixeldrain.com/api), leaking the user's API key to the malicious actor via the Authorization header.
// impactAnyone who has setup a Pixeldrain API key with cyberdrop-dl-patched and uses cyberdrop-dl-patched on sites that could spawn downloads for other sites (ex: forums, Wordpress, Pixeldrain itself, etc...)
// patchescyberdrop-dl-patched v9.14.0 fixes this issue by rejecting any Pixedrain URL if the host does not match an official domain __exactly__.
// workaroundsIt's recommended to upgrade cyberdrop-dl-patched to version v9.14.0
Anyone who has used a Pixeldrain API key with cyberdrop-dl-patched should consider them compromised and delete them from their Pixeldrain account.
