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 was discovered when using Document Level Security and the SPO "Limited Access" functionality in Elastic Sharepoint Online Python Connector. If a user is assigned limited access permissions to an item on a Sharepoint site then that user would have read permissions to all content on the Sharepoint site through Elasticsearch.

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 Elastic SharePoint Online Python Connector incorrectly handles Document Level Security (DLS) when users have 'Limited Access' permissions in SharePoint Online. The connector fails to properly restrict access, granting these users read permissions to ALL content on the SharePoint site through Elasticsearch, rather than limiting them to only the specific items they are authorized to access.

MitigationUpdate the Document Level Security implementation in the SharePoint Online connector to properly recognize and restrict 'Limited Access' permissions, ensuring users only receive access to content they are explicitly authorized to view.

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 connector version
    Locate the installed Elastic SharePoint Online Python Connector and retrieve its version number. This is typically found in the connector's configuration, deployment manifest, or package metadata. Compare the version against the affected range: versions prior to 8.10.3.0 are vulnerable.
    Affected if The installed version is below 8.10.3.0
  2. Confirm Document Level Security is enabled
    Inspect the connector configuration for the Document Level Security (DLS) setting. DLS is typically a configuration flag or policy that controls whether access controls are applied to indexed content. Check if DLS is turned on or configured for the SharePoint Online connector.
    Affected if Document Level Security (DLS) is enabled in the connector configuration
  3. Verify SharePoint Online target and permission model
    Confirm the connector is configured to sync from a SharePoint Online environment. Check if the SharePoint site(s) being indexed utilize the 'Limited Access' permission level, which is a special permission in SharePoint Online that allows users to access specific items or libraries without seeing the entire site.
    Affected if The connector targets SharePoint Online and the source site contains users with 'Limited Access' permissions

You are affected if your Elastic SharePoint Online Python Connector version is below 8.10.3.0, Document Level Security is enabled, and your SharePoint Online environment includes users granted 'Limited Access' permissions, as these users could gain unintended read access to all site content.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 8.10.3.0 or later
Fixed in 8.10.3.0
Interim mitigation

Update the Document Level Security implementation in the SharePoint Online connector to properly recognize and restrict 'Limited Access' permissions, ensuring users only receive access to content they are explicitly authorized to view.

Recommended fix Moderate confidence

8.10.3.0

  1. Identify the current version of the Elastic Sharepoint Online Python Connector in use
  2. Stop any services or processes currently running the connector
  3. Upgrade the connector to version 8.10.3.0 or later using the standard Elastic upgrade procedure
  4. Verify the new version is installed correctly by checking the connector version
  5. Restart the connector services
  6. Confirm that Document Level Security with SPO Limited Access now properly restricts user access to only authorized items
