PYSEC-2026-458 Pipecat: Remote Code Execution by Pickle Deserialization Through LivekitFrameSerializer

Remote Code Execution via Unsafe Deserialization in Pipecat's LivekitFrameSerializer Summary A critical vulnerability exists in Pipecat's LivekitFrameSerializer – an optional, non-default, undocumented frame serializer class now deprecated intended for LiveKit integration. The class's deserialize...

PYSEC-2026-456 PickleScan's pkgutil.resolve_name has a universal blocklist bypass

Summary pkgutil.resolvename is a Python stdlib function that resolves any "module:attribute" string to the corresponding Python object at runtime. By using pkgutil.resolvename as the first REDUCE call in a pickle, an attacker can obtain a reference to ANY blocked function e.g., os.system,...

PYSEC-2026-312 Ckan remote code execution and private information access via crafted resource ids

Specific vulnerabilities: Arbitrary file write in resourcecreate and packageupdate actions, using the ResourceUploader object. Also reachable via packagecreate, packagerevise, and packagepatch via calls to packageupdate. Remote code execution via unsafe pickle loading, via Beaker's session store...

PYSEC-2026-547 Deserialization of untrusted data in synthcity

A vulnerability, which was classified as critical, has been found in vanderSchaar LAB synthcity 0.2.9. Affected by this issue is the function loadfromfile of the component PKL File Handler. The manipulation leads to deserialization. The attack may be launched remotely. The exploit has been...

PYSEC-2026-327 DeepDiff Class Pollution in Delta class leading to DoS, Remote Code Execution, and more

Summary Python class pollution is a novel vulnerability categorized under CWE-915. The Delta class is vulnerable to class pollution via its constructor, and when combined with a gadget available in DeltaDiff itself, it can lead to Denial of Service and Remote Code Execution via insecure Pickle...

PYSEC-2026-503 pyquokka is Vulnerable to Remote Code Execution by Pickle Deserialization via FlightServer

Description In the FlightServer class of the pyquokka framework, the doaction method directly uses pickle.loads to deserialize action bodies received from Flight clients without any sanitization or validation, which results in a remote code execution vulnerability. The vulnerable code is located...

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,...

vLLM Allows Remote Code Execution via PyNcclPipe Communication Service

Impacted EnvironmentsThis issue ONLY impacts environments using the PyNcclPipe KV cache transfer integration with the V0 engine. No other configurations are affected. SummaryvLLM supports the use of thePyNcclPipeclass to establish a peer-to-peer communication domain for data transmission between...

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-2026-367 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....

PYSEC-2026-545 OpenStack Object Storage (swift) Code Injection vulnerability

OpenStack Object Storage swift before 1.7.0 uses the loads function in the pickle Python module unsafely when storing and loading metadata in memcached, which allows remote attackers to execute arbitrary code via a crafted pickle object...
