## What is CVE-2024-3271?

CVE-2024-3271 is a critical command injection vulnerability in run-llama/llama_index, published on 16 Apr 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official 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.

Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command)

Check this codebase for CVE-2024-3271 and fix it if it is affected.

What it is: CVE-2024-3271 is a critical command injection vulnerability in run-llama/llama_index, published on 16 Apr 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-3271 exists.

Affected packages and fixed versions:
- llama-index-core (PyPI): affected all versions; fixed in 0.10.24
- llama-index-core (PyPI): affected all versions; fixed in 0.10.24
- llama-index-core (PyPI): affected all versions; fixed in 0.10.24

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
