Flowise through 2.2.7 fails to sanitize path segments in the document-store loader endpoint, allowing unauthenticated attackers to write files outside the storage directory. Attackers can use parent-directory sequences to escape the storage directory and overwrite application files loaded at boot for remote code execution.

Each line links to the index that lists it, never to exploit code. Exploit-DB's "verified" and a Metasploit rank of good or better count as verified; a PoC-in-GitHub entry is a repository's claim.
