Summary

IBM Langflow OSS from 1.0.0 through 1.12.2 deserializes untrusted cache data (CWE-502). An attacker who holds the server secret and has write access to Redis can submit a malicious serialized cache value. When the service retrieves that value, deserialization executes attacker-controlled code with the privileges of the service process.

Description from the CNA

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.
