CVE-2026-54254 Details

Description

Cyberdrop-DL is a bulk asynchronous downloader for multiple file hosts. From 8.5.0 until 9.14.0, the Pixeldrain crawler uses substring host matching instead of requiring the input host to be an exact member of SUPPORTED_DOMAINS, and then reuses that input host for API requests. When a Pixeldrain API key is configured, processing a crafted URL from an attacker-controlled lookalike host causes cyberdrop_dl/crawlers/pixeldrain.py to send the Authorization header to that host. The URL may be introduced through a third-party site that can cause downloads for other sites, and the attacker receives the user's Pixeldrain API key. This issue is fixed in version 9.14.0.
