CVE-2025-32227Network attack vector

Subscriber upload-limit bypass via modified requests

Published Apr 10, 2025 · Updated Apr 29, 2026

Authentication bypass in Asgaros Forum 3.0.0 and earlier allows remote authenticated users to upload more attachments than configured. The attachment-upload path in affected releases accepts client-modified requests with more files than the configured per-post maximum instead of enforcing the count server-side. Subscriber access is required; the demonstrated consequence is excess file storage, with no reported code execution or data disclosure.
