CVE-2025-22734 Overview
CVE-2025-22734 is a stored cross-site scripting (XSS) vulnerability in the Data443 Risk Mitigation, Inc. Posts Footer Manager plugin (intelly-posts-footer-manager) for WordPress. The flaw affects all versions up to and including 2.1.0. The plugin fails to properly neutralize user-supplied input during web page generation, allowing an authenticated attacker with high privileges to inject persistent JavaScript payloads. Because the scope changes [CWE-79], the injected script executes against other users who view affected pages, including site administrators.
Critical Impact
Attackers with high privileges can store malicious scripts that execute in visitors' browsers, enabling session theft, administrative action hijacking, and site defacement.
Affected Products
- Data443 Posts Footer Manager (intelly-posts-footer-manager) WordPress plugin
- All versions from initial release through 2.1.0
- WordPress sites running the vulnerable plugin with authenticated contributor-level or higher accounts
Discovery Timeline

Technical Details for CVE-2025-22734
Vulnerability Analysis
The vulnerability resides in the input-handling logic of the Posts Footer Manager plugin. The plugin accepts footer content from privileged users and writes it into post output without sufficient sanitization or output encoding. When an administrator or editor saves footer content containing HTML or JavaScript, the plugin persists it to the database and later renders it inline on front-end pages.
Because the stored payload executes in the browser context of every visitor who loads affected posts, the impact extends beyond the authenticated attacker. The scope-changed classification reflects that injected scripts run in a security context distinct from the one used to inject them. For technical specifics, consult the Patchstack Vulnerability Report.
Root Cause
The root cause is improper neutralization of input during web page generation [CWE-79]. The plugin does not apply WordPress sanitization functions such as wp_kses_post() on input or esc_html() / esc_attr() on output. As a result, raw markup containing <script> tags or event-handler attributes is preserved and rendered.
Attack Vector
Exploitation requires network access, high privileges, and user interaction. An authenticated attacker with sufficient role permissions saves a crafted footer entry containing JavaScript. The payload is stored in the WordPress database. When a victim loads any post that renders the footer, the browser executes the attacker-controlled script, potentially stealing cookies, performing actions as the victim, or redirecting to attacker-controlled infrastructure.
No verified public exploit code is available for this vulnerability. See the referenced advisory for additional context.
Detection Methods for CVE-2025-22734
Indicators of Compromise
- Unexpected <script> tags, inline event handlers (onerror, onload), or obfuscated JavaScript stored in Posts Footer Manager configuration tables
- Outbound HTTP requests from site visitors to unknown third-party domains originating from footer-rendered pages
- WordPress audit log entries showing footer content modifications by compromised or unexpected administrative accounts
Detection Strategies
- Review the plugin's stored footer entries for HTML or JavaScript that was not placed intentionally by site operators
- Scan rendered pages with an automated DOM-inspection tool to flag inline scripts injected via the plugin
- Correlate WordPress role changes and plugin configuration events with unusual outbound traffic from visitor sessions
Monitoring Recommendations
- Enable WordPress audit logging for plugin option updates and content modifications performed by privileged users
- Monitor web server access logs for anomalous referrers or requests to credential-harvesting endpoints originating from affected posts
- Alert on Content Security Policy (CSP) violation reports that identify inline script execution on pages using the plugin
How to Mitigate CVE-2025-22734
Immediate Actions Required
- Identify all WordPress instances running the Posts Footer Manager plugin and verify installed versions against 2.1.0
- Audit existing footer configuration entries for injected HTML or script content and remove any unauthorized payloads
- Rotate credentials for all administrator and editor accounts, and review recent privileged account activity for signs of abuse
Patch Information
At the time of publication, no fixed version is listed in the referenced advisory. Monitor the Patchstack Vulnerability Report and the vendor's plugin page for updates and apply the patched release as soon as it becomes available.
Workarounds
- Deactivate and remove the Posts Footer Manager plugin until a patched version is released
- Restrict high-privilege WordPress roles to a minimal, trusted set of users and enforce multi-factor authentication for those accounts
- Deploy a Content Security Policy that disallows inline scripts and restricts script sources to trusted origins
- Place a web application firewall (WAF) in front of the WordPress site with rules that block stored XSS payloads targeting plugin configuration endpoints
