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
Some endpoints in vulnerability-lookup that modified application state (e.g. changing database entries, user data, configurations, or other privileged actions) may have been accessible via HTTP GET requests without requiring a CSRF token. This flaw leaves the application vulnerable to Cross-Site Request Forgery (CSRF) attacks: an attacker who tricks a logged-in user into visiting a malicious website could cause the user’s browser to issue GET requests that perform unintended state-changing operations in the context of their authenticated session. Because the server would treat these GET requests as valid (since no CSRF protection or POST method enforcement was in place), the attacker could exploit this to escalate privileges, change settings, or carry out other unauthorized actions without needing the user’s explicit consent or awareness.  The fix ensures that all state-changing endpoints now require HTTP POST requests and include a valid CSRF token. This enforces that state changes cannot be triggered by arbitrary cross-site GET requests. This issue affects Vulnerability-Lookup: before 2.18.0.

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

CSRF vulnerability in Vulnerability-Lookup allows attackers to trigger state-changing operations (database modifications, user data changes, configuration updates) via HTTP GET requests without CSRF tokens. Attackers can trick authenticated users into visiting malicious sites that issue unintended GET requests performing privileged actions in the user's session context.

MitigationUpgrade to version 2.18.0 or later which enforces HTTP POST requests with valid CSRF tokens for all state-changing endpoints. Until upgraded, monitor for unauthorized state changes and consider disabling affected functionality.

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. Confirm Vulnerability-Lookup installation
    Identify if Vulnerability-Lookup application is running in your environment by checking for the web service on its typical port (default 5000/tcp) or by querying running processes for the application binary/service
    Affected if Vulnerability-Lookup is present and running in the environment
  2. Determine installed version
    Query the application's version endpoint (typically /api/version or /about) via HTTP GET request, or check the installed package version via package manager if installed via package distribution
    Affected if Installed version is lower than 2.18.0 (the fixed release)
  3. Identify state-changing endpoints accessible via GET
    Review application routing configuration or API documentation to enumerate endpoints that perform database modifications, user data changes, or configuration updates
    Affected if State-changing endpoints are accessible via HTTP GET method without requiring POST with CSRF token
  4. Test for CSRF protection on GET requests
    Send an authenticated HTTP GET request to a known state-changing endpoint (e.g., user creation, configuration update, data deletion) and observe whether the request succeeds without a CSRF token in the request headers or body
    Affected if GET requests to state-changing endpoints succeed without CSRF token validation (vulnerable condition)
  5. Inspect CSRF token configuration
    Check the application's configuration files or source code for CSRF middleware settings, specifically whether GET requests to state-changing routes are protected or exempt
    Affected if CSRF protection is not enforced on GET requests to state-changing endpoints

A user is affected if Vulnerability-Lookup version below 2.18.0 is running and HTTP GET requests to state-changing endpoints execute without requiring CSRF token validation.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to version 2.18.0 or later which enforces HTTP POST requests with valid CSRF tokens for all state-changing endpoints. Until upgraded, monitor for unauthorized state changes and consider disabling affected functionality.

Recommended fix High confidence

2.18.0

  1. Identify the current version of vulnerability-lookup currently deployed
  2. Upgrade vulnerability-lookup to version 2.18.0 or later
  3. Verify the upgrade was successful by checking the version number
  4. Confirm that state-changing endpoints now require HTTP POST requests with valid CSRF tokens
