critical Web App Scanning Plugin ID 115466

Synopsis

LiteLLM < 1.84.0 Multiple Vulnerabilities

Description

According to its self-reported version, the instance of LiteLLM running on the remote web server is prior to 1.84.0. It is, therefore, affected by multiple vulnerabilities :

- An Authentication Bypass through OAuth2 Passthrough Fallback (CVE-2026-59822).

- An Authentication Bypass via Host Header Injection (CVE-2026-49468).

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to LiteLLM version 1.84.0 or later.
