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
Collabora Online is a collaborative online office suite based on LibreOffice. A stored cross-site scripting vulnerability was found in Collabora Online. An attacker could create a document with an XSS payload in document text referenced by field which, if hovered over to produce a tooltip, could be executed by the user's browser. Users should upgrade to Collabora Online 23.05.10.1 or higher. Earlier series of Collabora Online, 22.04, 21.11, etc. are unaffected.

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

Collabora Online contains a stored cross-site scripting vulnerability where an attacker can embed malicious JavaScript in document text that gets referenced by a field. When users hover over the affected field to display a tooltip, the embedded XSS payload executes in the victim's browser context.

MitigationUpgrade to Collabora Online version 23.05.10.1 or later. Organizations on earlier branches (22.04, 21.11) are unaffected and do not require action.

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 Collabora Online installation
    Check the product version through the admin interface of the WOPI host (e.g., Nextcloud or ownCloud admin panel), or query the /hosting/capabilities endpoint if accessible, or run 'docker ps' to identify the Collabora container and check its image tag
    Affected if Running a container or installation with a version tag visible in the output
  2. Determine installed version number
    For Docker: run 'docker images' and note the image tag or digest. For native packages: check the package manager (apt list --installed | grep collabora or similar). Compare the version to 23.05.10.1
    Affected if Installed version is below 23.05.10.1 (e.g., 23.05.9, 23.05.8, etc.)
  3. Verify document editing is enabled
    Confirm that the Collabora Online service is active and users can upload and edit documents through the WOPI host interface. Check that the 'Edit' functionality is available for supported document types (ODT, DOCX, etc.)
    Affected if Users can create or edit documents through the Collabora Online interface
  4. Confirm field insertion feature is accessible
    This vulnerability affects fields with tooltips. In document editing interfaces, fields can be inserted via Insert > Field commands in the toolbar. Check if users have access to document editing functions that allow field insertion and tooltip text
    Affected if Users have permission to insert and edit fields in documents

You are affected if your Collabora Online version is below 23.05.10.1 and users can edit documents with field tooltip functionality enabled.
