CVE-2025-71338
Flowise through 2.2.7 - Arbitrary File Write to Remote Code Execution via document-store API
Description
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.
