CVE-2021-20403
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 · uneditedIBM Security Verify Information Queue 1.0.6 and 1.0.7 is vulnerable to cross-site request forgery which could allow an attacker to execute malicious and unauthorized actions transmitted from a user that the website trusts.
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 confidenceIBM Security Verify Information Queue versions 1.0.6 and 1.0.7 contain a Cross-Site Request Forgery (CSRF) vulnerability. This allows attackers to trick authenticated users into unknowingly executing unauthorized actions by leveraging the trusted relationship between the user and the application.

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.
-
Identify installed version of IBM Security Verify Information QueueCheck the product version through the admin console, installation directory metadata, or by querying the application server for the deployed IBM Security Verify Information Queue build informationAffected if The installed version is 1.0.6 or 1.0.7
-
Inspect forms and API endpoints for anti-CSRF tokensReview HTML forms and AJAX requests in the application for the presence of CSRF tokens or unique session identifiers that are validated server-side on state-changing operationsAffected if State-changing operations lack anti-CSRF token validation
-
Verify SameSite cookie attributesExamine the session cookies Set-Cookie headers or cookie configuration to confirm SameSite attribute is set to Strict or Lax, not set to None without Secure flag, or missing entirelyAffected if Cookies lack proper SameSite attribute configuration
-
Check Origin and Referer header validationReview server-side code or configuration to determine if incoming requests are validated against an allowlist for Origin/Referer headers before processing state-changing requestsAffected if The application does not validate Origin or Referer headers on requests
You are affected if IBM Security Verify Information Queue version 1.0.6 or 1.0.7 is running AND the application lacks proper CSRF protections such as anti-CSRF tokens, SameSite cookie attributes, or Origin/Referer header validation.

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 anti-CSRF tokens for state-changing operations, configure SameSite cookie attributes, and validate Origin/Referer headers to prevent forged requests.
