Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The /api/files/extract-text endpoint in parisneo/lollms up to v2.2.0 lacks authentication enforcement, missing the Depends(get_current_active_user) dependency present on other file endpoints. This allows unauthenticated users to upload and process files, enabling resource exhaustion DoS attacks and potential information disclosure.

MitigationAdd the Depends(get_current_active_user) authentication dependency to the /api/files/extract-text endpoint to enforce authentication consistent with other file-related endpoints.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Lollms version
    Identify the installed version of parisneo/lollms (e.g., check package.json, docker image tag, or application metadata) and compare it to the affected range: <= 2.1.0
    Affected if The installed version is 2.1.0 or earlier, or any version up to and including 2.2.0
  2. Verify the /api/files/extract-text endpoint exists
    Confirm that the Lollms instance exposes the /api/files/extract-text API endpoint (check API documentation, route definitions, or attempt a request to the endpoint)
    Affected if The endpoint is exposed and accessible in the environment
  3. Test endpoint authentication requirement
    Send an unauthenticated HTTP request to /api/files/extract-text (or the full path such as /api/files/extract-text) without providing valid authentication credentials (no Bearer token, session cookie, or API key) and observe the response
    Affected if The endpoint accepts the request and returns a successful response (200 OK) instead of returning a 401 Unauthorized or 403 Forbidden error, indicating authentication is not enforced
  4. Compare authentication on similar file endpoints
    Send unauthenticated requests to other file-related endpoints (such as /api/files/upload, /api/files/list, or similar) and verify they properly require authentication (expect 401/403 responses)
    Affected if Other file endpoints correctly reject unauthenticated requests but /api/files/extract-text does not, confirming the missing Depends(get_current_active_user) dependency

A user is affected if running Lollms version 2.1.0 or earlier (or any version up to 2.2.0) and the /api/files/extract-text endpoint accepts unauthenticated requests while other file endpoints properly enforce authentication.

Interim mitigation

Add the Depends(get_current_active_user) authentication dependency to the /api/files/extract-text endpoint to enforce authentication consistent with other file-related endpoints.

Recommended fix High confidence

Lollms version 2.2.1 or later

  1. 1. Back up your current Lollms installation and any important data
  2. 2. Review the vendor fix at commit a6625dc83786ff21d109b0d545ca61b770607ef3 which adds Depends(get_current_active_user) to the /api/files/extract-text endpoint
  3. 3. Upgrade Lollms to a version that includes this fix (version 2.2.1 or later)
  4. 4. After upgrade, verify the /api/files/extract-text endpoint now requires authentication by attempting an unauthenticated request
  5. 5. Confirm other file-related endpoints continue to function with proper authentication
