CVE-2025-22357 Overview
CVE-2025-22357 is a reflected cross-site scripting (XSS) vulnerability in the wpdever Target Notifications WordPress plugin. The flaw affects all versions of target-notifications up to and including 1.1.1. The plugin fails to properly neutralize user-supplied input during web page generation, allowing attackers to inject malicious scripts that execute in the victim's browser context [CWE-79].
Exploitation requires user interaction, typically by tricking an authenticated user into clicking a crafted link. Successful exploitation can lead to session theft, credential harvesting, and unauthorized actions performed on behalf of the victim.
Critical Impact
Attackers can execute arbitrary JavaScript in the victim's browser, potentially compromising WordPress administrator sessions and pivoting to full site takeover.
Affected Products
- wpdever Target Notifications plugin for WordPress
- All versions through 1.1.1
- WordPress sites with the target-notifications plugin installed and active

Technical Details for CVE-2025-22357
Vulnerability Analysis
The Target Notifications plugin reflects attacker-controlled input from HTTP request parameters back into the rendered HTML response without applying output encoding or input sanitization. When a victim loads a URL containing crafted payload data, the browser parses the injected content as executable JavaScript within the trusted origin of the WordPress site.
Reflected XSS in a WordPress plugin context is particularly impactful because the executed script inherits the privileges of the currently authenticated user. If the victim is a site administrator, the attacker can leverage REST API endpoints, modify plugin settings, create new administrative accounts, or inject persistent backdoors into theme files.
The scope-changed designation in the CVSS vector indicates that the vulnerable component can affect resources beyond its security boundary, meaning the injected script operates in the broader WordPress application context.
Root Cause
The root cause is improper neutralization of input during web page generation [CWE-79]. The plugin code paths handling request parameters do not apply WordPress sanitization functions such as esc_html(), esc_attr(), or wp_kses() before echoing user-controlled values into HTML output. Without these protective wrappers, raw <script> tags and event handler attributes pass through to the response.
Attack Vector
The attack requires no authentication and is exploitable over the network. The attacker crafts a URL targeting a vulnerable endpoint of the target-notifications plugin, embedding a JavaScript payload in a reflected parameter. The attacker delivers this URL through phishing emails, malicious advertisements, or compromised third-party sites.
When the victim clicks the link while logged into the WordPress site, the malicious script executes with the victim's session privileges. Refer to the Patchstack Vulnerability Report for the specific parameter and endpoint details.
Detection Methods for CVE-2025-22357
Indicators of Compromise
- HTTP request logs containing URL-encoded <script> tags, javascript: URIs, or onerror= event handlers targeting plugin endpoints
- Unexpected outbound connections from administrator browser sessions to attacker-controlled domains
- Creation of new WordPress administrator accounts without corresponding audit trail entries
- Modifications to theme files, plugin settings, or wp_options table that do not match scheduled administrative activity
Detection Strategies
- Inspect web server access logs for requests to target-notifications plugin paths containing suspicious query string patterns such as encoded angle brackets or quote characters
- Deploy a Web Application Firewall (WAF) with rules detecting reflected XSS payloads in query parameters and POST bodies
- Monitor Content Security Policy (CSP) violation reports for inline script execution attempts on WordPress admin pages
Monitoring Recommendations
- Enable WordPress audit logging plugins to track user creation, role changes, and plugin configuration modifications
- Forward web server and WordPress logs to a centralized SIEM for correlation across administrative sessions
- Alert on anomalous administrator activity originating from unusual IP addresses or geolocations shortly after link clicks
How to Mitigate CVE-2025-22357
Immediate Actions Required
- Identify all WordPress instances running the target-notifications plugin at version 1.1.1 or earlier
- Deactivate and remove the Target Notifications plugin until a patched release is verified
- Force a password reset and session invalidation for all WordPress administrator accounts
- Review WordPress user lists and recent content changes for signs of unauthorized modification
Patch Information
At the time of publication, the vulnerability affects Target Notifications versions through 1.1.1 with no fixed version documented in the NVD record. Monitor the Patchstack Vulnerability Report and the WordPress plugin repository for vendor updates. Apply the fixed version as soon as it becomes available.
Workarounds
- Remove or disable the target-notifications plugin entirely if it is not business-critical
- Deploy WAF rules blocking common XSS payload patterns targeting the plugin's request parameters
- Enforce a strict Content Security Policy that disallows inline script execution on WordPress administrative interfaces
- Train administrators to avoid clicking unverified links while authenticated to the WordPress admin console
