Privileged upload of dangerous files

Published Dec 20, 2023 · Updated Apr 28, 2026

Unrestricted file upload in Symbiostock 6.0.0 and earlier allows remote authenticated users to place dangerous files on a WordPress site. Public records do not identify the upload handler, accepted file field, storage path, or validation operation that permits the file type. High-privilege WordPress access is required, and the published evidence does not establish whether an uploaded file is web-accessible or executable.
