Exploitation Status

No confirmed exploitation observed yet

  • A successful exploit gives an attacker total control of the affected component, not partial access.
  • CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

Impact

The /config/update endpoint does not enforce admin role authorization. A user who is already authenticated into the platform can then use this endpoint to do the following:

  • Modify proxy configuration and environment variables
  • Register custom pass-through endpoint handlers pointing to attacker-controlled Python code, achieving remote code execution
  • Read arbitrary server files by setting UI_LOGO_PATH and fetching via /get_image
  • Take over other priveleged accounts by overwriting UI_USERNAME and UI_PASSWORD environment variables

Patches

Fixed in v1.83.0. The endpoint now requires proxy_admin role.

Workarounds

Restrict API key distribution. There is no configuration-level workaround.

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update litellm to 1.83.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-53mr-6c8q-9789 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-53mr-6c8q-9789 can be triaged on real exposure rather than presence alone.

Tailored to GHSA-53mr-6c8q-9789. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

How to detect GHSA-53mr-6c8q-9789

A community-maintained Nuclei template exists for this CVE. You can scan for it directly:

nuclei -id ghsa-53mr-6c8q-9789 -u https://target
Template
LiteLLM - Arbitrary File Read
Severity
high
Impact
Authenticated users can execute arbitrary code, read server files, and take over privileged accounts, leading to full system compromise.
Remediation
Update to version 1.83.0 or later.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Red HatImportant

This Important flaw in LiteLLM allows an authenticated user to bypass authorization on the `/config/update` endpoint. This enables modification of proxy configurations and environment variables, leading to remote code execution, unauthorized file access, and potential account takeover. Red Hat Ansible Automation…
