Unsafe Deserialization vulnerability in Modular Max Serve before 25.6, specifically when the "--experimental-enable-kvcache-agent" feature is used allowing attackers to execute arbitrary code...

PYSEC-2026-566 vLLM Deserialization of Untrusted Data vulnerability

vllm-project vllm version v0.6.2 contains a vulnerability in the MessageQueue.dequeue API function. The function uses pickle.loads to parse received sockets directly, leading to a remote code execution vulnerability. An attacker can exploit this by sending a malicious payload to the MessageQueue,...

PYSEC-2026-351 H2O Deserialization of Untrusted Data Vulnerability

A vulnerability in the h2oai/h2o-3 REST API versions 3.46.0.4 allows unauthenticated remote attackers to execute arbitrary code via deserialization of untrusted data. The vulnerability exists in the endpoints POST /99/ImportSQLTable and POST /3/SaveToHiveTable, where user-controlled JDBC URLs are...

PYSEC-2026-567 vLLM Allows Remote Code Execution via PyNcclPipe Communication Service

Impacted Environments This issue ONLY impacts environments using the PyNcclPipe KV cache transfer integration with the V0 engine. No other configurations are affected. Summary vLLM supports the use of the PyNcclPipe class to establish a peer-to-peer communication domain for data transmission...

PYSEC-2026-253 AgentScope Deserialization Vulnerability

A vulnerability in the RpcAgentServerLauncher class of modelscope/agentscope v0.0.6a3 allows for remote code execution RCE via deserialization of untrusted data using the dill library. The issue occurs in the AgentServerServicer.createagent method, where serialized input is deserialized using...

PYSEC-2026-295 BentoML deserialization vulnerability

A deserialization vulnerability exists in BentoML's runner server in bentoml/bentoml versions =1.3.4.post1. By setting specific parameters, an attacker can execute unauthorized arbitrary code on the server, causing severe harm. The vulnerability is triggered when the args-number parameter is...

PYSEC-2026-568 vLLM deserialization vulnerability in vllm.distributed.GroupCoordinator.recv_object

vllm-project vllm version 0.6.0 contains a vulnerability in the distributed training API. The function vllm.distributed.GroupCoordinator.recvobject deserializes received object bytes using pickle.loads without sanitization, leading to a remote code execution vulnerability. Maintainer perspective...

PYSEC-2026-510 Qiskit allows arbitrary code execution decoding QPY format versions < 13

Impact A maliciously crafted QPY file can potentially execute arbitrary-code embedded in the payload without privilege escalation when deserializing QPY formats 13. A python process calling Qiskit's qiskit.qpy.load function could potentially execute any arbitrary Python code embedded in the corre...

PYSEC-2026-367 Kedro deserialization vulnerability

A Remote Code Execution RCE vulnerability has been identified in the Kedro ShelveStore class version 0.19.8. This vulnerability allows an attacker to execute arbitrary Python code via deserialization of malicious payloads, potentially leading to a full system compromise. The ShelveStore class use...

PYSEC-2026-526 rpc.py vulnerable to Deserialization of Untrusted Data

rpc.py through 0.6.0 allows Remote Code Execution because an unpickle occurs when the "serializer: pickle" HTTP header is sent. In other words, although JSON not Pickle is the default data format, an unauthenticated client can cause the data to be processed with unpickle. Per the maintainer, rpc....
