CVE-2025-47520 Overview
CVE-2025-47520 is a stored Cross-Site Scripting (XSS) vulnerability in the Syed Balkhi Charitable WordPress plugin. The flaw stems from improper neutralization of user-supplied input during web page generation [CWE-79]. It affects all versions of Charitable up to and including 1.8.5.1.
An authenticated attacker with high privileges can inject malicious JavaScript that persists in the application. When another user views the affected page, the injected script executes in their browser session. The scope change indicates the payload can impact resources beyond the vulnerable component.
Critical Impact
Stored XSS enables session hijacking, credential theft, and unauthorized actions on behalf of victim users, including site administrators.
Affected Products
- Syed Balkhi Charitable plugin for WordPress
- All versions from n/a through 1.8.5.1
- WordPress sites running the vulnerable plugin

Technical Details for CVE-2025-47520
Vulnerability Analysis
The Charitable plugin fails to properly sanitize and encode user-supplied input before rendering it in HTML output. This allows an attacker to embed executable JavaScript into stored fields processed by the plugin. Once stored, the payload executes whenever the affected view is rendered in a browser.
Exploitation requires authenticated access with elevated privileges and user interaction to trigger the payload. Despite these prerequisites, the stored nature of the flaw means the payload executes repeatedly across sessions and users. The changed scope allows the injected script to affect resources managed by other components, such as the WordPress admin interface.
Root Cause
The root cause is missing or insufficient output encoding when the plugin renders user-controlled data. WordPress provides sanitization helpers such as esc_html(), esc_attr(), and wp_kses(), but the vulnerable code paths in Charitable did not apply these consistently. As a result, HTML and JavaScript control characters pass through unchanged into the DOM.
Attack Vector
The attack vector is network-based through the WordPress web interface. An attacker with high-privilege access submits crafted input containing JavaScript through a plugin field that stores and later renders the value. When a victim, such as an administrator, loads the affected page, the browser parses the injected markup and executes the attacker's script under the site's origin.
The vulnerability mechanism is described in the Patchstack XSS Vulnerability Report. No public proof-of-concept exploit code is verified as available for this CVE.
Detection Methods for CVE-2025-47520
Indicators of Compromise
- Unexpected <script> tags, event handlers (onerror, onload), or JavaScript URIs stored in Charitable plugin fields or database tables
- Outbound HTTP requests from administrator browsers to unfamiliar domains after visiting Charitable pages
- Creation of new WordPress administrator accounts or unexpected changes to user roles following visits to plugin-managed pages
Detection Strategies
- Review the WordPress database (wp_posts, wp_postmeta, and Charitable-specific tables) for HTML entities and script fragments in fields that should contain plain text
- Enable and monitor Content Security Policy (CSP) violation reports to identify unauthorized inline script execution
- Audit WordPress user activity logs for high-privilege accounts submitting content containing HTML markup
Monitoring Recommendations
- Deploy a Web Application Firewall (WAF) with rules that inspect POST parameters submitted to /wp-admin/ endpoints for XSS payload patterns
- Log and alert on administrator session anomalies such as unexpected AJAX calls, cookie access patterns, or privilege changes
- Track plugin version inventory across WordPress installations to identify hosts running Charitable 1.8.5.1 or earlier
How to Mitigate CVE-2025-47520
Immediate Actions Required
- Upgrade the Charitable plugin to a version newer than 1.8.5.1 as soon as a patched release is available from the vendor
- Restrict high-privilege WordPress accounts and enforce multi-factor authentication to reduce the attacker's ability to meet the exploitation prerequisites
- Review recent submissions to Charitable-managed fields for unsanitized HTML or script content and remove any suspicious entries
Patch Information
Refer to the Patchstack XSS Vulnerability Report for the current patch status and vendor guidance. Sites should apply plugin updates through the WordPress admin dashboard or via wp-cli once a fixed version is published.
Workarounds
- Temporarily deactivate the Charitable plugin if a patched version is not yet available and the feature is not business-critical
- Deploy virtual patching through a WAF such as Patchstack, Wordfence, or Cloudflare to block XSS payloads targeting plugin endpoints
- Implement a strict Content Security Policy that disallows inline scripts and untrusted script sources to reduce payload execution impact
# Update Charitable plugin using wp-cli once a patched version is released
wp plugin update charitable
# Alternatively, deactivate the plugin as a temporary workaround
wp plugin deactivate charitable
