3Description
A vulnerability in parisneo/lollms, up to and including version 2.2.0, allows unauthenticated users to upload and process files through the `/api/files/extract-text` endpoint. This endpoint does not enforce authentication, unlike other file-related endpoints, and lacks the `Depends(get_current_active_user)` dependency. This issue can lead to denial of service (DoS) through resource exhaustion, information disclosure, and violation of the application's documented security policies.
Analysis
Unauthenticated file upload in parisneo/lollms versions ≤2.2.0 enables remote attackers to submit arbitrary files for text extraction without authentication via the `/api/files/extract-text` endpoint. The vulnerability (CWE-287: Improper Authentication) allows resource exhaustion DoS attacks and potential information disclosure, with CVSS 7.5 (High) reflecting network-accessible attack surface requiring no privileges. …

Remediation
Within 24 hours: Identify all systems running ParisNeo LOLLMS ≤2.2.0 and document their network exposure; implement network-level access controls (firewall rules, WAF policies) to restrict access to `/api/files/extract-text` to trusted internal networks only. Within 7 days: Deploy runtime monitoring on LOLLMS instances to detect unusual file upload patterns and resource consumption spikes; consider disabling the text extraction feature entirely if not operationally required. …
