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
An issue in Doccano Open source annotation tools for machine learning practitioners v.1.8.4 and Doccano Auto Labeling Pipeline module to annotate a document automatically v.0.1.23 allows a remote attacker to escalate privileges via the model_attribs parameter.

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 · moderate confidence

Doccano v1.8.4 and the Doccano Auto Labeling Pipeline module v0.1.23 contain a privilege escalation vulnerability in which the model_attribs parameter can be manipulated by a remote attacker to elevate their privileges within the application.

MitigationRestrict and validate the model_attribs parameter on all endpoints, implement proper authorization checks, and upgrade to patched versions when available.

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 Doccano installation and version
    Run 'pip show doccano' or check the application's package/version metadata to determine if Doccano is installed and note its version number
    Affected if The installed version is v1.8.4 or lower (unpatched)
  2. Identify Doccano Auto Labeling Pipeline module version
    Run 'pip show doccano-auto-labeling' or check the installed packages to determine the version of the auto-labeling pipeline module
    Affected if The installed version is v0.1.23 or lower (unpatched)
  3. Verify model_attribs parameter exposure
    Review application endpoint configurations, API routes, and any custom routing that accepts the model_attribs parameter; check logs or request patterns for model_attribs usage
    Affected if The model_attribs parameter is accepted and processed by any API endpoint without strict validation
  4. Check for privilege escalation indicators
    Review application audit logs, user permission changes, or role modifications that occurred without proper authorization; query the database for users with elevated roles assigned by unexpected sources
    Affected if Users have gained elevated privileges (admin, superuser, or elevated roles) through the model_attribs parameter mechanism

A user is affected if running Doccano v1.8.4 or Auto Labeling Pipeline v0.1.23 or lower AND the application accepts and processes the model_attribs parameter without strict validation, allowing privilege escalation.
