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
MaxKB is an open-source AI assistant for enterprise. Prior to 2.9.0, MaxKB's webhook trigger endpoint (/api/trigger/v1/webhook/{trigger_id}) is accessible without authentication. The WebhookAuth class unconditionally returns (None, {}), which Django REST Framework interprets as successful authentication. Combined with optional per-trigger token verification and no backend enforcement of token requirements, any unauthenticated attacker who knows a valid trigger ID can invoke webhook triggers to execute their bound tasks. This vulnerability is fixed in 2.9.0.

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

MaxKB versions prior to 2.9.0 have an unauthenticated webhook trigger endpoint at /api/trigger/v1/webhook/{trigger_id}. The WebhookAuth class returns (None, {}) which Django REST Framework treats as successful authentication, allowing any attacker with a valid trigger ID to execute bound webhook tasks without any credentials.

MitigationUpgrade to MaxKB 2.9.0 or later which implements proper authentication enforcement in the WebhookAuth class. If immediate upgrade is not possible, disable webhook triggers or implement external authentication controls.

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. Identify MaxKB version
    Check the installed MaxKB version by reviewing the application's version file, Docker image tag, or running a version query command against the API
    Affected if version is lower than 2.9.0 (the fixed release)
  2. Confirm webhook endpoint is accessible
    Verify that the /api/trigger/v1/webhook/{trigger_id} endpoint is exposed and reachable from the network
    Affected if the webhook trigger endpoint is externally or internally accessible without authentication required
  3. Check if trigger IDs exist
    Review the MaxKB configuration or database for any configured webhook trigger IDs that could be exploited
    Affected if any valid trigger_id values are present in the system that could be used to invoke the vulnerable endpoint
  4. Test authentication behavior
    Send a request to the webhook endpoint with a known trigger_id but without any authentication headers or tokens
    Affected if the request succeeds and executes the bound task without returning an authentication error

A user is affected if running MaxKB version lower than 2.9.0 with the webhook trigger endpoint accessible and at least one valid trigger ID configured in the system

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to MaxKB 2.9.0 or later which implements proper authentication enforcement in the WebhookAuth class. If immediate upgrade is not possible, disable webhook triggers or implement external authentication controls.

Recommended fix High confidence

2.9.0

  1. Upgrade MaxKB to version 2.9.0 or later to resolve the authentication bypass in the webhook trigger endpoint (/api/trigger/v1/webhook/{trigger_id})
