CVE-2024-1063Network attack vector

Unauthenticated blind SSRF via favicon URL fetching

Published Jan 30, 2024 · Updated May 29, 2025

SSRF in Appwrite 1.4.13 and earlier allows remote attackers to trigger blind server-side requests through the favicon endpoint. Tenable identifies /v1/avatars/favicon as the locus and states that it bypasses the earlier SSRF fix, but no underlying filter or parsing defect is disclosed. No authentication or user interaction is required; impact is limited to server-originated requests and confidentiality, with no reported integrity or availability effect.
