GHSA-72m8-9m7m-h278

Fix: BerriAI/litellm@e50b448

GHSA-72m8-9m7m-h278 is a Code Injection vulnerability in litellm. O3 Security confirms whether GHSA-72m8-9m7m-h278 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description

Impact

LiteLLM's Custom Code Guardrails production create/update paths did not apply the same sandboxing and validation used by the test endpoint.

A privileged user with access to create or update guardrails could submit custom Python code that executed in the LiteLLM proxy environment. In deployments without a configured master key, callers could be treated as proxy administrators, making this reachable without intended administrative authorization.

This could allow arbitrary code execution in the LiteLLM proxy container and exposure of secrets available to the process.

Patches

The issue is fixed in 1.82.0-stable.

LiteLLM recommend upgrading to 1.82.0-stable or later.

Workarounds

If upgrading is not immediately possible:

  1. Restrict access to POST /guardrails and PUT /guardrails/{guardrail_id} to trusted administrators only.
  2. Ensure LITELLM_MASTER_KEY is configured.
  3. Avoid enabling Custom Code Guardrails for untrusted users.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for litellm. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update litellm to 1.82.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-72m8-9m7m-h278 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-72m8-9m7m-h278 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-72m8-9m7m-h278. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
