CVE-2026-7871Network attack vector

Code execution via unsigned Redis cache deserialization

Published Jun 30, 2026 · Updated Jun 30, 2026

Insecure deserialization in IBM Langflow OSS 1.0.0 through 1.10.0 allows remote attackers with Redis access to execute arbitrary code. The Redis cache service passes unsigned cache values to dill.loads(), so a crafted serialized object executes when any worker reads it. Reachability requires network access to the configured Redis instance; execution inherits the Langflow application's privileges and access to its secrets and data.
