Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to version 1.5.1, the helper in branched on the setting to decide whether to filter by . When was (i.e., authentication was enabled), neither branch enforced an ownership check — the query returned any flow matching the given UUID regardless of who owned it. This allowed any authenticated user to read any other user's flow, including embedded plaintext API keys; modify the logic of another user's AI agents, and/or delete flows belonging to other users. The vulnerability was introduced by the conditional logic that was meant to accommodate public/example flows (those with ) under auto-login mode, but inadvertently left the authenticated path without an ownership filter. The fix in version 1.5.1 removes the conditional entirely and unconditionally scopes the query to the requesting user.
