IBM Langflow OSS 1.0.0 through 1.12.2 could allow an attacker with access to the server secret and Redis write access to submit a malicious serialized cache value. When the value was retrieved, deserialization could have executed attacker-controlled code with the privileges of the service process.
IBM strongly recommends addressing the vulnerability now by upgrading Langflow OSS to version 1.12.3. https://pypi.org/project/langflow/#description
