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.
