CVE-2023-3796Network attack vector

Arbitrary file upload via profile picture handler

Published Jul 20, 2023 · Updated Aug 2, 2024

Unrestricted file upload in Foody Friend 1.0 allows remote authenticated users to store arbitrary files through the profile page. The /user/profile endpoint accepts the profile_picture parameter without restricting dangerous file types, although public sources do not identify the responsible function or storage path. A valid user session is required; the CNA establishes unauthorized file placement but does not establish code execution or data disclosure.
