CVE-2025-59344Network attack vector

Internal resource disclosure via favicon extraction SSRF

Published Sep 19, 2025 · Updated Sep 19, 2025

Server-side request forgery in the AliasVault API before 0.23.1 allows remote authenticated users to retrieve internal images. The favicon extractor fetches a user-supplied HTTP(S) URL, follows icon links and redirects without rejecting loopback or private destinations, and returns valid images as Base64. Exploitation requires a self-hosted, internet-reachable instance with public registration enabled; it exposes image data and permits internal-service mapping through timing and errors.
