CVE-2025-30565
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 karrikas banner-manager banner-manager allows Stored XSS.This issue affects banner-manager: from n/a through <= 16.04.19.
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 confidenceCSRF vulnerability in karrikas banner-manager enables attackers to trick authenticated users into performing unintended actions that inject malicious scripts, resulting in Stored XSS. The lack of anti-CSRF tokens in form submissions allows attackers to craft malicious requests that persist malicious code in the banner manager.

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 karrikas banner-manager installationSearch for the banner-manager component in your application's codebase or deployed files. Look for directories or modules named 'banner-manager' or 'karrikas'. Check your package.json, composer.json, or other dependency manifests for 'karrikas/banner-manager' or similar naming.Affected if The karrikas banner-manager component is found in your environment
-
Determine banner-manager versionCheck your dependency lock files (package-lock.json, composer.lock, Gemfile.lock) or the banner-manager source code for a version string. Compare this version against any official release notes or changelog from the vendor.Affected if The installed version has no anti-CSRF protection implemented in form handling
-
Inspect form submissions for anti-CSRF tokensNavigate to the banner-manager admin interface and examine the HTML source of any form (create/edit banner, upload, settings). Look for input elements with names like 'csrf_token', '_token', 'csrf', or 'xsrf' within the form tags. Also check request headers for CSRF-related headers.Affected if Forms in the banner-manager lack anti-CSRF token fields or validation
-
Verify CSRF protection in backend form handlingExamine the server-side code that handles banner-manager form submissions. Check if the controller or handler validates CSRF tokens before processing state-changing requests (POST/PUT/DELETE). Look for middleware or decorators that enforce CSRF protection.Affected if The backend does not validate CSRF tokens on banner-manager form handlers
-
Test for Stored XSS via CSRFUsing an authenticated session, submit a form in the banner-manager with a test payload like '<script>alert(1)</script>' as a banner name or description. If the payload persists and executes when viewing the banner, the XSS is present and likely exploitable via CSRF.Affected if Malicious scripts submitted through unauthenticated (CSRF) requests persist and execute in the banner manager interface
Your environment is affected if the karrikas banner-manager is installed and form submissions lack anti-CSRF token validation, allowing attackers to trick authenticated users into injecting persistent malicious scripts.

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 on all state-changing operations and apply context-aware output encoding/escaping to neutralize stored malicious scripts before rendering.
