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
Cross-site request forgery vulnerability exists in Musetheque V4 Information Disclosure for IPKNOWLEDGE V4L1 rev2203.0 and earlier. If a user views a malicious page while logged-in to the affected product, unexpected operations may be done.

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

Cross-site request forgery (CSRF) vulnerability in Musetheque V4 allows attackers to craft malicious pages that, when visited by authenticated users, can trigger unintended operations on the affected IPKNOWLEDGE V4L1 application due to missing or insufficient anti-CSRF protections on state-changing requests.

MitigationImplement anti-CSRF tokens or SameSite cookie attributes on all state-changing endpoints, and validate the Origin/Referer headers to prevent cross-site request forgery attacks.

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 if Musetheque V4 / IPKNOWLEDGE V4L1 is installed
    Check running processes, deployed applications, or installed packages for references to Musetheque V4 or IPKNOWLEDGE V4L1. Inspect web server configurations, application directories, or service listings.
    Affected if The Musetheque V4 or IPKNOWLEDGE V4L1 application is found running in the environment
  2. Determine the installed version of Musetheque V4
    Check application metadata files, version banners, or configuration files for the exact version number. Compare against any available version documentation.
    Affected if The installed version is Musetheque V4 (any version) and the application handles state-changing requests
  3. Inspect state-changing endpoints for anti-CSRF token presence
    Review the HTML forms or API endpoints that perform state-changing operations (such as data creation, modification, or deletion). Examine the HTML source or API request structure to determine if anti-CSRF tokens are included in the requests.
    Affected if State-changing endpoints lack anti-CSRF tokens in their request parameters or headers
  4. Verify Origin or Referer header validation
    Capture a state-changing request using a proxy or browser dev tools, then attempt to send the request with a mismatched or missing Origin/Referer header. Alternatively, inspect server-side code or configuration for Origin/Referer validation logic.
    Affected if The application accepts state-changing requests without validating the Origin or Referer headers
  5. Check SameSite cookie attributes on session cookies
    Inspect the Set-Cookie headers or cookie definitions in the application configuration. Look for the SameSite attribute on authentication or session cookies.
    Affected if Session cookies lack the SameSite attribute or have it set to None without Secure flag

The environment is affected if Musetheque V4 or IPKNOWLEDGE V4L1 is running and any state-changing endpoints lack anti-CSRF tokens, do not validate Origin/Referer headers, or use cookies without proper SameSite attributes.
