CVE-2025-40706
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 · uneditedCross-Site Scripting (XSS) vulnerability in OpenAtlas v8.9.0 from the Austrian Centre for Digital Humanities and Cultural Heritage (ACDH-CH), due to inadequate validation of user input when a POST request is sent. The vulnerabilities could allow a remote user to send specially crafted queries to an authenticated user and steal their session cookie details, via the "/insert/source" petition, "name" 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 · high confidenceCross-Site Scripting (XSS) vulnerability in OpenAtlas v8.9.0 where the 'name' parameter in the '/insert/source' POST endpoint fails to properly validate or sanitize user input, allowing injection of malicious script that executes in authenticated users' browsers to steal session cookies.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm OpenAtlas installationIdentify whether the Craws OpenAtlas application is deployed in your environment. Check for the OpenAtlas web application, its installation directory, or running service.Affected if OpenAtlas is not installed in your environment
-
Verify the exact version numberLocate and inspect the installed version of OpenAtlas. Check the application source files, configuration, or admin interface for the version string. Compare it to the affected version 8.9.0.Affected if The installed version is 8.9.0 exactly
-
Confirm /insert/source endpoint existsCheck if the /insert/source POST endpoint is available in your OpenAtlas deployment. This may require reviewing application routing configuration or attempting to access the endpoint.Affected if The /insert/source endpoint exists and responds to POST requests
-
Verify authentication is requiredDetermine whether the /insert/source endpoint requires valid user authentication to access. Test if unauthenticated requests are rejected or if the endpoint is accessible only to logged-in users.Affected if The endpoint requires authentication (authenticated users can access it)
-
Check name parameter handlingIf accessible, examine how the 'name' parameter is processed at the /insert/source endpoint. Verify if user-supplied input in this parameter is reflected back in responses without sanitization.Affected if The 'name' parameter accepts user input that is reflected in responses without proper encoding
You are affected if you have Craws Openatlas version 8.9.0 running with the /insert/source endpoint accessible to authenticated users.

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.
From vendor dataImplement proper input validation and output encoding for the 'name' parameter at the /insert/source endpoint, and add Content-Security-Policy headers to mitigate XSS risks.
