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. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires three concurrent conditions: (1) the victim has configured a Pixeldrain API key in cyberdrop-dl-patched; (2) the victim processes a URL whose host contains 'pixeldrain' as a substring but is not an official Pixeldrain domain - this URL must reach the tool either directly or spawned from another site being scraped (e.g., a forum, WordPress site, or aggregator); and (3) the attacker controls the malicious domain and can log incoming HTTP requests. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is moderate but highly context-dependent. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers the domain evil-pixeldrain.com and configures it to log all incoming HTTP Authorization headers. They post a download link to https://evil-pixeldrain.com/u/SomeFileID on a forum or file-sharing aggregator site that cyberdrop-dl-patched users frequently scrape. … |
| Remediation | Upgrade cyberdrop-dl-patched to version 9.14.0 or later via pip (pip install --upgrade cyberdrop-dl-patched). … Detailed patch versions, workarounds, and compensating controls in full report. |
