CVE-2026-54254Network attack vector

API key disclosure via substring host matching

Published Sep 15, 2026 · Updated Sep 15, 2026

Improper host validation in Cyberdrop-DL 8.5.0 through 9.13.0 allows remote attackers to steal Pixeldrain API keys via crafted URLs. The Pixeldrain crawler treats any hostname containing a supported domain as valid, reuses the untrusted hostname for API requests, and attaches the Authorization header. A configured Pixeldrain API key and processing of a crafted URL supplied through a third-party site are required; the attacker receives the key.
