SCA: security update for pipecat-ai (GHSA-c2jg-5cp7-6wc7)

critical Tenable Self-Hosted Container Security Plugin ID 440781

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Pipecat is an open-source Python framework for building real-time voice and multimodal conversational
 agents. Versions 0.0.41 through 0.0.93 have a vulnerability in `LivekitFrameSerializer` – an optional,
 non-default, undocumented frame serializer class (now deprecated) intended for LiveKit integration. The
 class's `deserialize()` method uses Python's `pickle.loads()` on data received from WebSocket clients
 without any validation or sanitization. This means that a malicious WebSocket client can send a crafted
 pickle payload to execute arbitrary code on the Pipecat server. The vulnerable code resides in
 `src/pipecat/serializers/livekit.py` (around line 73), where untrusted WebSocket message data is passed
 directly into `pickle.loads()` for deserialization. If a Pipecat server is configured to use
 LivekitFrameSerializer and is listening on an external interface (e.g. 0.0.0.0), an attacker on the
 network (or the internet, if the service is exposed) could achieve remote code execution (RCE) on the
 server by sending a malicious pickle payload. Version 0.0.94 contains a fix. Users of Pipecat should avoid
 or replace unsafe deserialization and improve network security configuration. The best mitigation is to
 stop using the vulnerable LivekitFrameSerializer altogether. Those who require LiveKit functionality
 should upgrade to the latest Pipecat version and switch to the recommended `LiveKitTransport` or another
 secure method provided by the framework. Additionally, always follow secure coding practices: never trust
 client-supplied data, and avoid Python pickle (or similar unsafe deserialization) in network-facing
 components. (CVE-2025-62373)

Solution

Update the pipecat-ai library and its related packages to version 0.0.94 or later.
