CVE-2026-6344Network attack vector

Administrator file read via attachment path traversal

Published May 6, 2026 · Updated May 6, 2026

Path traversal in WPManageNinja Fluent Forms 6.2.1 and earlier allows remote authenticated users with administrator access to read local files. EmailNotificationActions::getAttachments converts attacker-supplied upload URLs into paths after a bypassable raw-prefix check, without canonicalizing traversal segments or confirming containment in the uploads directory. Exploitation requires an administrator-configured notification with a file-upload attachment; readable files are sent only to the configured notification recipient.
