CVE-2024-53750
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 Maeve Lander PayPal Responder allows Stored XSS.This issue affects PayPal Responder: from n/a through 1.2.
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 PayPal Responder enables attackers to inject persistent XSS payloads by tricking authenticated administrators into clicking malicious links. The stored XSS executes when other users view the compromised data, allowing session hijacking or further attacks.

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 PayPal Responder installation and versionLocate the PayPal Responder component in your web application (typically found in plugin directories, /wp-content/plugins/ for WordPress, or application modules). Check for version information in the component's main file header, changelog, or version metadata file.Affected if The installed version cannot be determined or is unknown/unpatched.
-
Verify CSRF token presence on state-changing operationsInspect HTML forms and AJAX endpoints that perform state-changing actions (data submission, configuration changes, user data updates). Examine the source code of forms that handle admin-submitted data to determine if a CSRF token field or header is present and validated on submission.Affected if Forms/submissions lack CSRF token generation and server-side validation.
-
Check input sanitization on data storage pathsReview the code paths where admin-submitted data is stored in the database. Look for sanitization functions (such as htmlspecialchars, strip_tags, or appropriate encoding functions) applied to data before database insertion.Affected if User-supplied data is stored without sanitization or encoding.
-
Inspect output encoding when data is renderedExamine the code that retrieves and displays stored data to users. Check if output encoding is applied when rendering admin-submitted content in browser-facing pages.Affected if Stored data is rendered without proper output encoding/escaping.
-
Confirm authenticated admin access is required for injectionVerify that the vulnerable data submission endpoint requires administrator-level authentication. This confirms the attack vector requires an authenticated admin to trigger the CSRF-based injection.Affected if The submission endpoint accepts requests from authenticated administrators without CSRF protection.
Your environment is affected if PayPal Responder is installed, lacks CSRF token validation on data submission forms, and does not properly sanitize/encode stored data before output rendering.

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 CSRF tokens on state-changing operations and apply proper input sanitization and output encoding to prevent XSS storage and execution.
