CVE-2024-8953 is a critical-severity flaw (CVSS 9.8) affecting composio. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In composiohq/composio version 0.4.3, the mathematical_calculator endpoint uses the unsafe eval() function to perform mathematical operations. This can lead to arbitrary code execution if untrusted input is passed to the eval() function.

composio composio DOWNGRADE

Affected: 0.4.3

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.4.3

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.4.3 (Debian / Ubuntu)

apt-cache madison composio sudo apt install composio=<VERSION_BEFORE_0.4.3> sudo apt-mark hold composio

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list composio sudo dnf downgrade composio-<VERSION_BEFORE_0.4.3> sudo dnf versionlock add composio

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.
