      <title>GHSA-53mr-6c8q-9789 — LiteLLM: Privilege escalation via unrestricted proxy configuration endpoint</title>
      <link>https://vulnerability.circl.lu/vuln/ghsa-53mr-6c8q-9789</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; PyPI: litellm&lt;/p&gt;
&lt;p&gt;### Impact&lt;/p&gt;
&lt;p&gt;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:&lt;/p&gt;
&lt;p&gt;- 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&lt;/p&gt;
&lt;p&gt;### Patches&lt;/p&gt;
&lt;p&gt;Fixed in v1.83.0. The endpoint now requires `proxy_admin` role.&lt;/p&gt;
&lt;p&gt;### Workarounds&lt;/p&gt;
&lt;p&gt;Restrict API key distribution. There is no configuration-level workaround.&lt;/p&gt;</description>
