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 F12-Profiler allows remote attackers to induce authenticated users into performing unintended actions by tricking their browsers into sending malicious requests to 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 F12-Profiler versionLocate the F12-Profiler installation directory and check version.txt, package.json, or the application's about/info page for the exact version numberAffected if The installed version matches or falls within any known affected version range for CVE-2025-27340 (if such a range is published)
-
Inspect state-changing endpoints for anti-CSRF tokensUse browser developer tools or a proxy to capture POST, PUT, or DELETE requests to the application. Examine the request body and headers for a unique, unpredictable token (e.g., csrf_token, _token, XSRF-TOKEN) that is submitted with each state-changing requestAffected if State-changing requests lack anti-CSRF tokens in the request parameters or headers
-
Verify Origin or Referer header validationCapture HTTP requests using a proxy and inspect the server-side code or server logs to determine if the application validates the Origin or Referer HTTP headers and rejects requests from untrusted originsAffected if The application does not validate Origin or Referer headers before processing state-changing requests
-
Check SameSite cookie configurationInspect the Set-Cookie headers in the application's HTTP responses using browser developer tools or a proxy. Verify if session or authentication cookies have the SameSite attribute set to Strict or LaxAffected if Authentication cookies lack the SameSite attribute or are set to None without secure flag
A user is affected if the installed F12-Profiler version is within the affected range and the application lacks anti-CSRF token validation on state-changing operations AND does not validate Origin/Referer headers.

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 (synchronizer token pattern) on all state-changing operations and validate Origin/Referer HTTP headers to ensure requests originate from legitimate sources.
