CVE-2025-22520
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 Request Forgery (CSRF) vulnerability in Tock Tock Widget tock-widget allows Cross Site Request Forgery.This issue affects Tock Widget: from n/a through <= 1.1.
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 confidenceCross-Site Request Forgery (CSRF) vulnerability in Tock Widget tock-widget version 1.1 and below allows attackers to induce authenticated users to perform unintended actions. The CVSS 7.1 score indicates the exploit is relatively easy to execute and can lead to unauthorized state-changing operations.

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 if tock-widget is present in your environmentSearch your codebase, dependencies, or installed packages for 'tock-widget' as a library or moduleAffected if tock-widget is found as a dependency or installed component
-
Determine the installed version of tock-widgetCheck your package.json, requirements.txt, Gemfile, or equivalent dependency manifest for the tock-widget version entry, or run a package manager query such as 'npm list tock-widget' or 'pip show tock-widget'Affected if the version is 1.1 or lower, or if no version is specified and the package is present
-
Verify if state-changing endpoints lack anti-CSRF tokensInspect the source code for form submissions or API POST/PUT/DELETE requests; check if each includes a hidden CSRF token field or token header that is validated server-sideAffected if state-changing requests (POST/PUT/DELETE) do not require and validate a unique anti-CSRF token
-
Check SameSite cookie configuration for session cookiesExamine your session cookie settings; look for SameSite attribute being set to 'None', 'Lax', or missing entirely rather than 'Strict'Affected if session cookies have SameSite set to 'None' or omitted, allowing cross-origin cookie transmission
-
Inspect origin/referer validation on state-changing actionsReview your server-side validation logic to confirm each state-changing endpoint validates the Origin or Referer header against an allowed listAffected if no origin or referer header validation is performed before processing state-changing requests
You are affected if tock-widget version 1.1 or below is installed AND your implementation lacks anti-CSRF token validation AND your session cookies permit cross-origin transmission.

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 or SameSite cookie attributes for all state-changing requests, and consider adding origin/referer validation as defense-in-depth.
