CVE-2026-0772Network attack vectorHinoki check available

Authenticated code execution via unsafe cache deserialization

Published Jan 23, 2026 · Updated Jan 23, 2026

Deserialization of untrusted data in Langflow OSS 1.5.0.post2 allows remote authenticated users to execute code through the disk cache service. The disk cache service accepts user-supplied serialized data without validating it before deserialization, allowing embedded object behavior to run. A valid account and network access to the service are required, and successful exploitation runs code with the service account's privileges.
