CVE-2025-2483 Overview
CVE-2025-2483 is a Reflected Cross-Site Scripting (XSS) vulnerability in the Gift Certificate Creator plugin for WordPress. The flaw affects all versions up to and including 1.1.0. It stems from insufficient input sanitization and output escaping on the receip_address parameter. Unauthenticated attackers can inject arbitrary web scripts that execute in a victim's browser when the victim clicks a crafted link. The vulnerability is tracked under [CWE-79]: Improper Neutralization of Input During Web Page Generation.
Critical Impact
Unauthenticated attackers can execute arbitrary JavaScript in a victim's browser session, enabling session theft, credential harvesting, or forced administrative actions on WordPress sites running the vulnerable plugin.
Affected Products
- Gift Certificate Creator plugin for WordPress, all versions up to and including 1.1.0
- WordPress sites with the plugin installed and active
- Any user browsing a WordPress site with the vulnerable plugin present

Technical Details for CVE-2025-2483
Vulnerability Analysis
The Gift Certificate Creator plugin accepts the receip_address parameter through an HTTP request and reflects its contents back into a rendered page. The plugin does not sanitize input on receipt and does not escape output at the rendering stage. As a result, attacker-controlled markup and JavaScript flow directly into the response body.
Because the attack requires user interaction, exploitation typically involves phishing links or malicious content embedded on third-party sites. The Reflected XSS pattern allows the payload to execute in the context of the target WordPress site's origin. This grants the injected script access to cookies, DOM contents, and any authenticated session the victim holds with the site.
The scope-changed rating in the CVSS vector reflects that the injected script can affect resources beyond the vulnerable component, such as the browser's same-origin session data for the WordPress domain.
Root Cause
The root cause is a failure to apply WordPress sanitization primitives such as sanitize_text_field() on input and escaping helpers such as esc_html() or esc_attr() on output. The affected code path resides in giftcertificates.php around line 312, where the receip_address parameter is emitted into HTML without neutralization.
Attack Vector
An attacker crafts a URL pointing to the vulnerable endpoint with a malicious payload placed in the receip_address parameter. The attacker delivers this URL to a victim through email, chat, or a link on another site. When the victim clicks the link, the WordPress site echoes the payload back, and the browser executes the injected script under the site's origin. No authentication is required on the attacker's side, and no prior access to the target site is needed.
The vulnerability manifests in the parameter handling logic of the plugin. See the WordPress Plugin Code Review and the Wordfence Vulnerability Report for technical details.
Detection Methods for CVE-2025-2483
Indicators of Compromise
- HTTP requests containing the receip_address query or form parameter with values that include <script>, javascript:, event handlers such as onerror=, or encoded variants.
- Web server access logs showing referrers from unfamiliar domains preceding requests to the plugin's endpoints.
- Unexpected outbound requests from user browsers to attacker-controlled domains after visiting pages served by the plugin.
Detection Strategies
- Deploy web application firewall (WAF) rules that inspect the receip_address parameter for HTML tags, JavaScript keywords, and common XSS payload patterns.
- Review WordPress access logs for GET or POST requests to plugin endpoints containing suspicious character sequences such as %3Cscript%3E or onload=.
- Enumerate WordPress installations to identify sites running Gift Certificate Creator at version 1.1.0 or earlier.
Monitoring Recommendations
- Alert on anomalous request volumes targeting the Gift Certificate Creator endpoints, particularly from external referrers.
- Monitor browser telemetry and Content Security Policy (CSP) violation reports for script executions originating from unexpected inline sources.
- Track administrative session activity for signs of hijacking, such as logins from new IP addresses or user-agent strings shortly after link clicks.
How to Mitigate CVE-2025-2483
Immediate Actions Required
- Deactivate the Gift Certificate Creator plugin on all WordPress sites until a patched version is confirmed installed.
- Apply WAF signatures that block requests containing script-like content in the receip_address parameter.
- Enforce a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins.
Patch Information
At the time of publication, no fixed version is listed in the NVD entry for CVE-2025-2483. Administrators should consult the WordPress Plugin Developer Info page and the Wordfence Vulnerability Report for updates on remediation status.
Workarounds
- Remove the plugin from production sites if it is not business-critical.
- Restrict access to the vulnerable endpoints via .htaccess rules or reverse proxy configuration until a patch is available.
- Educate administrators and editors to avoid clicking untrusted links targeting the WordPress site while logged in.
