Technical description

An authentication bypass vulnerability exists in AnythingLLM v1.8.5 in via the /api/workspaces endpoint. The endpoint fails to implement proper authentication checks, allowing unauthenticated remote attackers to enumerate and retrieve detailed information about all configured workspaces. Exposed data includes: workspace identifiers (id, name, slug), AI model configurations (chatProvider, chatModel, agentProvider), system prompts (openAiPrompt), operational parameters (temperature, history length, similarity thresholds), vector search settings, chat modes, and timestamps.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
