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
Exposure of sensitive information in GroupSharing prior to version 13.6.13.3 allows remote attackers can force the victim to join the group.

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 GroupSharing Nextcloud app prior to version 13.6.13.3 has an information disclosure vulnerability that allows remote attackers to obtain sensitive information (likely group identifiers or tokens), which can then be exploited to force victim users to join groups without proper authorization.

MitigationUpgrade GroupSharing app to version 13.6.13.3 or later; review group membership logs for unauthorized additions and consider resetting sensitive group tokens if exposed.

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 GroupSharing app version in Nextcloud
    Navigate to Nextcloud admin panel > Apps > GroupSharing, or use occ command: 'occ app:list | grep -i groupsharing' to see installed version
    Affected if Installed version is lower than 13.6.13.3
  2. Inspect GroupSharing API endpoints
    Check Nextcloud logs (通常在 /var/log/nextcloud/nextcloud.log) for requests to GroupSharing endpoints that may reveal group identifiers or tokens
    Affected if Logs show unauthenticated or unauthorized API calls exposing sensitive group data
  3. Review group membership audit logs
    Examine Nextcloud group management logs or audit logs for any group join operations initiated by unexpected users or without proper authorization
    Affected if There are group membership changes that were not initiated by authorized administrators
  4. Check for exposed group tokens
    Inspect the GroupSharing app configuration database table (oc_group_sharing or similar) for any tokens or identifiers that may be accessible without proper authentication
    Affected if Tokens or group identifiers are visible in plain text or accessible to unauthorized users
  5. Verify web server access logs
    Review web server access logs for suspicious requests to GroupSharing app endpoints, especially from unexpected IP addresses or unauthenticated sources
    Affected if External or unauthenticated requests are successfully retrieving group-related data

If the installed GroupSharing app version is below 13.6.13.3 and evidence exists of exposed group identifiers or unauthorized group membership changes, the environment is affected by this CVE.
