📄 Description

_process_picture_url validated the initial picture URL with validate_url() but then aiohttp followed 3xx redirects without re-validating the target, so a validate_url-passing public URL could 302 to an internal address and the body was base64-stored in the user's profile_image_url. This is the sixth call site of the CVE-2026-45401 redirect-bypass cohort; the other five already pass allow_redirects=AIOHTTP_CLIENT_ALLOW_REDIRECTS. Apply the same.
