CVSS 9.9 · Critical EPSS 0,97%

Kerentanan Deserialization of Untrusted Data pada langflow. Skor CVSS 3.1 9.9 (Critical) menurut us.ibm.com.

Deskripsi (NVD)

IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the disk-based caching mechanism. The AsyncDiskCache class uses Python's unsafe pickle.loads() function to deserialize cached objects from disk without validation, integrity verification, or authentication, enabling arbitrary code execution when malicious pickle payloads are processed. Attackers who can influence cached data through file system access, malicious workflow inputs, custom components, or API manipulation can achieve complete system compromise with the privileges of the Langflow server process.
