CVE-2025-32578 Overview
CVE-2025-32578 is a reflected Cross-Site Scripting (XSS) vulnerability in the Mapro Collins Coming Soon Countdown WordPress plugin (coming-soon-countdown). The flaw stems from improper neutralization of user-supplied input during web page generation [CWE-79]. All plugin versions up to and including 2.2 are affected. Attackers can craft malicious URLs that execute arbitrary JavaScript in a victim's browser when the user follows the link. The vulnerability requires user interaction and operates across a security scope boundary, allowing impact on resources beyond the vulnerable component.
Critical Impact
Successful exploitation allows attackers to execute arbitrary JavaScript in victim browsers, enabling session theft, credential harvesting, and WordPress administrator account compromise through crafted links.
Affected Products
- Mapro Collins Coming Soon Countdown WordPress plugin
- Plugin slug: coming-soon-countdown
- All versions up to and including 2.2

Technical Details for CVE-2025-32578
Vulnerability Analysis
The vulnerability is a reflected XSS flaw in the Coming Soon Countdown WordPress plugin. The plugin accepts user-controllable input through HTTP request parameters and reflects that input back into the generated HTTP response without proper sanitization or output encoding. When a victim clicks an attacker-crafted URL, the injected payload is rendered and executed in the context of the WordPress site.
Reflected XSS attacks against WordPress plugins commonly target administrators. If an authenticated administrator triggers the payload, the attacker can perform privileged actions including creating new admin accounts, modifying plugin settings, or injecting persistent backdoors into site content.
Root Cause
The root cause is missing input neutralization during web page generation. The plugin code does not apply WordPress sanitization functions such as esc_html(), esc_attr(), or wp_kses() to user-supplied data before embedding it in HTML output. This allows arbitrary HTML and JavaScript characters to break out of their intended context.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker crafts a URL containing a malicious JavaScript payload as a parameter value handled by the vulnerable plugin endpoint. The attacker distributes this link through phishing emails, social media, or compromised sites. When a victim with an active WordPress session follows the link, the browser executes the payload under the origin of the WordPress site. The changed scope means the executed script can affect resources beyond the plugin itself, including session cookies and authenticated administrator actions.

Detection Methods for CVE-2025-32578
Indicators of Compromise
- HTTP request logs containing JavaScript syntax such as <script>, onerror=, onload=, or javascript: in query parameters targeting plugin endpoints
- URL-encoded payload patterns such as %3Cscript%3E or %3Cimg in referer headers pointing to coming-soon-countdown paths
- Unexpected administrator account creation or privilege changes following plugin URL access
- Outbound requests from browsers to attacker-controlled domains after visiting WordPress pages hosting the plugin
Detection Strategies
- Inspect WordPress access logs for requests to the coming-soon-countdown plugin containing reflected parameter values with HTML or script syntax
- Deploy Web Application Firewall (WAF) rules that flag XSS payload patterns in query strings and POST bodies
- Monitor Content Security Policy (CSP) violation reports for inline script execution attempts on pages rendered by the plugin
- Correlate referer headers with suspicious external domains across multiple session events
Monitoring Recommendations
- Enable verbose request logging on the WordPress reverse proxy or WAF to capture full query strings
- Alert on WordPress administrator session activity originating from URLs containing the plugin path with encoded special characters
- Track plugin version inventory across WordPress deployments to identify unpatched installations of version 2.2 and earlier
How to Mitigate CVE-2025-32578
Immediate Actions Required
- Identify all WordPress instances running the Coming Soon Countdown plugin version 2.2 or earlier
- Deactivate and remove the plugin until a patched version is confirmed available from the vendor
- Force WordPress administrator password resets and invalidate active sessions if exploitation is suspected
- Review WordPress user accounts and recent content changes for unauthorized modifications
Patch Information
At the time of publication, no fixed version is listed in the advisory. The vulnerability affects all versions through 2.2. Monitor the Patchstack WordPress Vulnerability Report and the WordPress.org plugin repository for an updated release that addresses the input sanitization flaw.
Workarounds
- Remove or disable the coming-soon-countdown plugin from all WordPress installations
- Deploy WAF rules that block requests containing common XSS payload signatures targeting the plugin endpoint
- Implement a strict Content Security Policy (CSP) that disallows inline scripts and restricts script sources to trusted origins
- Educate administrators to avoid clicking untrusted links while authenticated to the WordPress admin panel
