CVE-2023-41055Public exploitNetwork attack vector

Blind SSRF and service interruption via language cookie

Published Sep 4, 2023 · Updated Sep 30, 2024

SSRF in LibreY before commit be59098abd119cda70b15bf3faac596dfd39a744 allows remote attackers to send arbitrary HTTP GET requests. The Google and DuckDuckGo text engines insert the unvalidated wikipedia_language cookie into a Wikipedia URL before passing it to cURL. No authentication or user interaction is required; a crafted cookie redirects the server to attacker-chosen hosts, exposes its origin IP, or exhausts resources by fetching large files.
