CVE-2026-108593 · Severity: medium · CVSS 6.4 · Published 2026-10-10

9router is an AI routing and token-saving service that manages requests to multiple AI providers. Authenticated dashboard users can inject malicious configuration into the Hermes Agent settings, allowing them to execute arbitrary shell commands after LLM calls without approval. This compromises the integrity of AI model interactions and enables code execution on the server.

## Technical details

A configuration injection vulnerability exists in the POST /api/cli-tools/hermes-settings endpoint where user-supplied input is not properly sanitized before being written to the Hermes Agent config.yaml file. An authenticated attacker can submit a baseUrl parameter containing double quotes and newlines to inject arbitrary keys, specifically hooks_auto_accept and hooks.post_llm_call with shell commands, which are executed without user approval.
