SCA: security update for langflow (GHSA-9c59-2mvc-vfr8)

high Tenable Cloud Security Plugin ID 443287

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.0, Langflow's
/api/v1/monitor router exposes 7 endpoints that perform read, write, and delete operations on user-owned
resources — messages, sessions, build artifacts, and LLM transaction logs — without verifying that the
authenticated requester owns the targeted resource. Any authenticated user can read, modify, rename, or
permanently delete another user's data by supplying the target's resource ID or flow_id. This is a classic
IDOR/BOLA vulnerability. Notably, the same source file (monitor.py) contains one correctly-implemented
endpoint that uses an ownership check, demonstrating the correct pattern was known but inconsistently
applied. This vulnerability is fixed in 1.9.0. (CVE-2026-33760)

Solution

Update the langflow library and its related packages to version 1.9.0 or later.
