CRITICAL 9.8REMOTEUPGRADE

CVE-2025-62373 is a critical-severity flaw (CVSS 9.8) affecting pipecat. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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.

pipecat pipecat UPGRADE

Affected: >= 0.0.41 and < 0.0.94

Fixed in: 0.0.94

Safe to downgrade to: a release before 0.0.41

1. Check installed version

apt-cache policy pipecat || rpm -q pipecat || pipecat --version

2. UPGRADE to 0.0.94 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade pipecat

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade pipecat

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 0.0.41 (Debian / Ubuntu)

apt-cache madison pipecat sudo apt install pipecat=<VERSION_BEFORE_0.0.41> sudo apt-mark hold pipecat

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list pipecat sudo dnf downgrade pipecat-<VERSION_BEFORE_0.0.41> sudo dnf versionlock add pipecat

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
