CVE-2026-33484 is a high-severity vulnerability affecting Langflow versions 1.0.0 through 1.8.1, allowing unauthenticated attackers to download any user's uploaded image files. This flaw stems from the `/api/v1/files/images/{flow_id}/{file_name}` endpoint serving images without proper authentication or ownership checks, enabling data leakage if a `flow_id` is known or guessed. Rated with a CVSS score of 7.5 (HIGH), it presents a high confidentiality impact with low attack complexity over the network. Currently, there is no evidence of active exploitation, nor are public exploit tools available, and community discussion remains minimal.
