## Summary An authenticated LiteLLM proxy user could read arbitrary local files from the proxy runtime by sending a crafted value to . The request-body safety blocklist rejected but missed its alias , which let the value reach the Vertex AI credential loader and trigger a file read that is sent to an attacker-controlled URL. ## Impact A low-privilege authenticated user (only , obtainable through SSO login on many deployments) could read any file readable by the LiteLLM process. Reading files such as can disclose and provider API keys, so the impact can escalate to full proxy-admin control. ## Remediation Upgrade to or later. The fix adds the missing alias to the request-body blocklist, so no configuration change is needed once you upgrade. There is no reliable configuration workaround on affected versions.
