What happened

## Summary

An authenticated LiteLLM proxy user could read arbitrary local files from the proxy runtime by sending a crafted `vertex_ai_credentials` value to `/utils/transform_request`. The request-body safety blocklist rejected `vertex_credentials` but missed its alias `vertex_ai_credentials`, 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 `internal_user_viewer`, obtainable through SSO login on many deployments) could read any file readable by the LiteLLM process. Reading files such as `/proc/self/environ` can disclose `LITELLM_MASTER_KEY` and provider API keys, so the impact can escalate to full proxy-admin control.

## Remediation

Upgrade to `1.95.0` 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.

Affected package ranges reported by GitHub: litellm: < 1.95.0

About this data

This record was ingested from a data source. Retrieved: Oct 27, 2026, 16:25 UTC. Ingestion is not an independent editorial investigation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.
