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 security vulnerability has been detected in jsbroks COCO Annotator up to 0.11.1. Affected by this vulnerability is an unknown functionality of the file backend/webserver/api/datasets.py of the component Dataset API. The manipulation of the argument DatasetId leads to authorization bypass. The attack may be initiated remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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

The vulnerability exists in the Dataset API (backend/webserver/api/datasets.py) of COCO Annotator up to v0.11.1, where manipulation of the DatasetId parameter allows attackers to bypass authorization checks. This broken access control vulnerability in the web application permits unauthorized access to or manipulation of datasets via the API endpoint.

MitigationImplement proper authorization validation for all dataset ID parameters in the API, verifying user permissions before allowing access or modifications to datasets. Until a vendor patch is available, consider network-level restrictions to limit API exposure.

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 COCO Annotator installation version
    Locate the installed COCO Annotator version - check the source code version file, package.json, or application metadata. Common locations include version info in the application UI or a version file in the root directory.
    Affected if The installed version is v0.11.1 or any earlier version (v0.x.x where x <= 11)
  2. Verify Dataset API component exists
    Inspect the backend/webserver/api/datasets.py file in the COCO Annotator installation directory. Confirm the file exists and contains the Dataset API implementation.
    Affected if The file backend/webserver/api/datasets.py exists in the installation
  3. Determine if web API is exposed
    Check if the COCO Annotator web application is running and accessible over HTTP/HTTPS. Identify the base URL for the API endpoints.
    Affected if The web application API is accessible (not restricted by firewall or network controls)
  4. Test DatasetId parameter authorization
    Send API requests to the dataset endpoint (typically /api/datasets/) with manipulated DatasetId values. Attempt to access or modify datasets belonging to other users without proper authentication credentials.
    Affected if API requests with arbitrary DatasetId values succeed without proper authorization validation (requests return dataset data or allow modifications without permission checks)

A user is affected if running COCO Annotator version v0.11.1 or earlier AND the web API is accessible AND the API permits unauthorized access/modification via DatasetId parameter manipulation.
