CVE-2023-41054Public exploitNetwork attack vector

Internal HTTP data disclosure via noncanonical URL parsing

Published Sep 4, 2023 · Updated Sep 30, 2024

SSRF in Ahwxorg LibreY before 8f9b9803f231e2954e5b49987a532d28fe50a627 allows remote attackers to read arbitrary HTTP response bodies. The get_root_domain function splits the supplied url parameter on slashes and treats the text after two slashes as the host, so noncanonical URLs pass the domain allowlist while the HTTP client requests a different destination. No authentication or user interaction is required; responses from internal HTTP services are returned, and large downloads can interrupt service.
