CVE-2025-24629 Overview
CVE-2025-24629 is a reflected Cross-Site Scripting (XSS) vulnerability in the Import Excel to Gravity Forms WordPress plugin developed by wpgear. The flaw is classified under CWE-79, Improper Neutralization of Input During Web Page Generation. The vulnerability affects all versions of the gf-excel-import plugin up to and including 1.18. An unauthenticated attacker can craft a malicious URL that, when clicked by a victim, executes arbitrary JavaScript in the victim's browser session within the WordPress site's origin.
Critical Impact
Successful exploitation requires user interaction but enables attackers to hijack administrator sessions, perform actions on behalf of authenticated users, and pivot to broader WordPress site compromise.
Affected Products
- wpgear Import Excel to Gravity Forms plugin (gf-excel-import)
- All versions from initial release through 1.18
- WordPress installations using this plugin with Gravity Forms

Technical Details for CVE-2025-24629
Vulnerability Analysis
The vulnerability is a reflected XSS issue in the gf-excel-import plugin. The plugin fails to properly neutralize user-supplied input before reflecting it back in HTTP responses generated by the WordPress backend. When a victim with an active WordPress session visits a crafted URL, attacker-controlled JavaScript executes in the browser under the trust context of the WordPress site.
Reflected XSS attacks rely on the victim clicking a malicious link delivered via phishing emails, chat messages, or attacker-controlled web pages. The scope-change indicator in the vulnerability's CVSS vector reflects that injected scripts can affect resources beyond the vulnerable component, such as cookies and DOM contents of the broader WordPress administrative interface.
Root Cause
The plugin reflects request parameters into HTML output without applying contextually appropriate output encoding. Developers did not call WordPress sanitization helpers such as esc_html(), esc_attr(), or wp_kses() on input before rendering it. As a result, payloads containing <script> tags or HTML event handlers are interpreted by the browser rather than treated as inert text.
Attack Vector
The attack requires no authentication but does require user interaction. An attacker crafts a URL pointing to a vulnerable endpoint in the gf-excel-import plugin with a JavaScript payload embedded in a reflected parameter. The attacker then delivers this URL to a target, typically a WordPress administrator. Upon loading the URL, the browser executes the payload, allowing the attacker to steal session cookies, perform CSRF-like actions, or inject content into the admin dashboard. See the Patchstack advisory for additional technical context.
Detection Methods for CVE-2025-24629
Indicators of Compromise
- Web server access logs containing requests to gf-excel-import endpoints with URL parameters that include <script>, javascript:, onerror=, or onload= strings
- Unexpected outbound requests from administrator browsers to attacker-controlled domains following plugin URL visits
- New or modified WordPress administrator accounts created shortly after suspicious URL access patterns
- URL-encoded XSS payload signatures such as %3Cscript%3E in HTTP query strings targeting the plugin
Detection Strategies
- Inspect web access logs for requests to plugin paths containing reflected parameters with HTML or JavaScript syntax
- Deploy a Web Application Firewall (WAF) with rules tuned for reflected XSS targeting WordPress plugin endpoints
- Monitor WordPress audit logs for administrative actions originating from unexpected IP addresses or user agents
Monitoring Recommendations
- Enable verbose logging on the WordPress site and forward logs to a centralized analytics platform for query and correlation
- Alert on any HTTP request to gf-excel-import endpoints containing angle brackets, JavaScript event handlers, or known XSS keywords
- Track Content Security Policy (CSP) violation reports to surface injection attempts even when payloads fail to execute
How to Mitigate CVE-2025-24629
Immediate Actions Required
- Identify all WordPress installations running the gf-excel-import plugin and confirm the installed version
- Disable or uninstall the plugin on any site running version 1.18 or earlier until a patched release is verified
- Rotate WordPress administrator credentials and invalidate active sessions if exploitation is suspected
Patch Information
At the time of NVD publication, the advisory indicates the vulnerability affects versions up to and including 1.18 with no fixed version specified. Site administrators should monitor the Patchstack advisory and the plugin's WordPress.org repository for an updated release that includes proper output encoding.
Workarounds
- Remove the gf-excel-import plugin from production sites until a patched version is released
- Deploy a WAF rule that blocks requests to plugin endpoints containing common XSS payload patterns such as <script, onerror=, and javascript:
- Enforce a restrictive Content Security Policy that disallows inline scripts to reduce the impact of reflected XSS payloads
- Restrict administrator access to the WordPress backend through IP allowlisting or VPN-gated authentication
# Example Apache WAF rule to block reflected XSS attempts targeting the plugin
SecRule REQUEST_URI "@contains /wp-content/plugins/gf-excel-import/" \
"chain,deny,status:403,id:1024629,msg:'Block XSS attempt on gf-excel-import'"
SecRule ARGS "@rx (?i)(<script|onerror=|onload=|javascript:)" "t:urlDecodeUni"
