Pixeldrain API key shared with unverified thirdparty sites
Summary
When processing Pixeldrain URLs, cyberdrop-dl-patched could send an Authorization header that includes the user's API key to unverified hosts.
Details
Pixeldrain 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.
Impact
Anyone 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...)
Patches
cyberdrop-dl-patched v9.14.0 fixes this issue by rejecting any Pixedrain URL if the host does not match an official domain exactly.
Workarounds
It'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.
