# CVE-2026-59819: LiteLLM: Local file read via request-supplied OIDC file references

## TL;DR
LiteLLM: Local file read via request-supplied OIDC file references

## Key Points
- cve / CVE-2026-59819 / PYSEC-2026-3476 / severity:CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N / litellm / PyPI

## Details
**Severity:** CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N
**Advisory:** PYSEC-2026-3476 (CVE-2026-59819)

**Affected (your watchlist):**
- `PyPI:litellm` 1.72.6.post2 → fixed in 1.83.10 [docker/docker-strands]

**Details:**
### Impact

LiteLLM's `/health/test_connection` endpoint resolved request-supplied environment and OIDC file references in `litellm_params`. A proxy administrator, or another privileged caller with permission to test model connections, could cause LiteLLM to read files from the local filesystem via an `oidc/file/` reference.

Because exploitation requires privileged proxy access, this is treated as a defense-in-depth issue rather than a cross-tenant privilege bypass.

### Patches

The issue is fixed in `1.83.10-stable`.

LiteLLM recommend upgrading to `1.83.10-stable` or later.

### Workarounds

Restrict `/health/test_connection` access to trusted administrators only.
