CVE-2025-28882 Overview
CVE-2025-28882 is a reflected cross-site scripting (XSS) vulnerability in the Omnify Widget plugin for WordPress, developed by Omnify, Inc. The flaw affects all plugin versions up to and including 2.0.3. Attackers can inject arbitrary JavaScript into responses generated by the plugin, which executes in the browser of any victim who clicks a crafted link. The vulnerability is tracked under CWE-79 and requires user interaction to trigger.
Critical Impact
Attackers can execute arbitrary JavaScript in a victim's browser session, enabling session hijacking, credential theft, and unauthorized actions against WordPress sites running vulnerable Omnify Widget installations.
Affected Products
- Omnify Widget WordPress plugin versions through 2.0.3
- WordPress sites with the omnify-widget plugin installed
- All deployments that have not applied the vendor remediation

Technical Details for CVE-2025-28882
Vulnerability Analysis
The Omnify Widget plugin fails to properly neutralize user-supplied input before reflecting it back in HTTP responses. This results in a reflected XSS condition where attacker-controlled payloads execute in the context of the targeted WordPress site. Because the issue has a changed scope, successful exploitation can affect resources beyond the vulnerable component, including authenticated user sessions and adjacent application contexts.
The attack requires the victim to interact with a malicious link, typically delivered through phishing or social engineering. Once triggered, the injected script executes with the privileges of the victim's browser session. This enables attackers to read session cookies, perform actions on behalf of the user, and pivot toward administrative accounts when a site administrator is targeted.
The vulnerability is exploitable over the network without authentication, lowering the barrier for opportunistic attacks against public-facing WordPress installations.
Root Cause
The root cause is improper neutralization of input during web page generation, classified as [CWE-79]. The plugin reflects request parameters into its output without applying contextual output encoding or sanitization. Standard WordPress escaping functions such as esc_html(), esc_attr(), and wp_kses() are not applied to the affected input paths.
Attack Vector
The vulnerability manifests when an attacker crafts a URL containing a malicious JavaScript payload in a parameter consumed by the Omnify Widget plugin. The victim must click the link while browsing a site running the vulnerable plugin. The server reflects the payload into the rendered page, where the browser parses and executes it. Refer to the Patchstack Vulnerability Report for technical details on the affected parameter and request flow.
Detection Methods for CVE-2025-28882
Indicators of Compromise
- HTTP requests to Omnify Widget endpoints containing <script>, javascript:, or HTML event handler strings such as onerror= and onload= in query parameters
- Web server access logs showing unusually long or URL-encoded payloads targeting plugin parameters
- Unexpected outbound requests from user browsers to attacker-controlled domains following clicks on links referencing the WordPress site
Detection Strategies
- Inspect WordPress access logs for requests to Omnify Widget routes containing reflected user input and script-like syntax
- Deploy web application firewall (WAF) rules that flag XSS payload signatures in query strings targeting the plugin
- Monitor browser-side Content Security Policy (CSP) violation reports for inline script execution on pages rendering Omnify Widget content
Monitoring Recommendations
- Enable verbose logging on the WordPress reverse proxy or CDN to capture full request URIs for forensic review
- Alert on referrer patterns indicating users arriving from external sites with suspicious query parameters
- Track plugin version inventory across WordPress estates to identify hosts still running Omnify Widget 2.0.3 or earlier
How to Mitigate CVE-2025-28882
Immediate Actions Required
- Identify all WordPress installations running the omnify-widget plugin and confirm installed versions
- Update the plugin to a version higher than 2.0.3 once the vendor publishes a fix, or disable the plugin until a patched release is available
- Apply WAF rules that block reflected XSS payloads targeting Omnify Widget endpoints
Patch Information
The vulnerability affects Omnify Widget versions through 2.0.3. Consult the Patchstack Vulnerability Report for the latest remediation status and any updated plugin releases issued by Omnify, Inc.
Workarounds
- Deactivate the Omnify Widget plugin until a patched release is verified
- Implement a strict Content Security Policy (CSP) that disallows inline scripts and restricts script sources to trusted origins
- Train administrators and editors to avoid clicking unsolicited links referencing the WordPress site, particularly when authenticated to wp-admin
# Example WordPress CLI commands to inventory and disable the affected plugin
wp plugin list --name=omnify-widget --fields=name,status,version
wp plugin deactivate omnify-widget
