Lifecycle Timeline

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.
AnalysisAI
Pixeldrain API key exfiltration in cyberdrop-dl-patched (versions 8.5.0 through 9.13.x) allows a network attacker who controls a lookalike domain (e.g., evil-pixeldrain.com) to receive the victim's Pixeldrain Authorization header when the tool processes a crafted URL. The root cause is substring-based host matching: any domain containing 'pixeldrain' as a substring is accepted as a valid Pixeldrain host, causing the tool to blindly send API credentials to attacker-controlled infrastructure. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog, but the attack path is straightforward and fully described in the advisory.
Technical ContextAI
cyberdrop-dl-patched is a Python pip package (pkg:pip/cyberdrop-dl-patched) that automates bulk downloading from file-hosting services including Pixeldrain. Pixeldrain supports alternative domains to circumvent ISP-level blocks (documented at docs.pixeldrain.com), so the tool was designed to dynamically derive the API host from the input URL rather than hardcode it. The crawler-matching logic uses substring containment rather than exact equality to associate an input URL's host with the appropriate crawler. CWE-20 (Improper Input Validation) is the root cause: the host value extracted from user-supplied URLs is not validated against an allowlist of known-good Pixeldrain domains before being used to construct authenticated API requests. The patch in commit 4479555a introduces a SUPPORTED_DOMAINS exact-match check in _prepare_headers within cyberdrop_dl/crawlers/pixeldrain.py, raising a ValueError and rejecting the request if the host is not an officially recognized Pixeldrain domain.
RemediationAI
Upgrade cyberdrop-dl-patched to version 9.14.0 or later via pip (pip install --upgrade cyberdrop-dl-patched). The release is available at https://github.com/Cyberdrop-DL/cyberdrop-dl/releases/tag/9.14.0. Additionally, any Pixeldrain API key used with prior versions should be treated as compromised: revoke and regenerate it immediately through the Pixeldrain account settings. There is no effective workaround short of upgrading, since the flaw is in the host-matching logic itself. As a partial compensating control, users can avoid running the tool against untrusted aggregator sites or community forums until upgraded, which reduces the likelihood of encountering a malicious URL.
