CVE-2025-23601 Overview
CVE-2025-23601 is a reflected Cross-Site Scripting (XSS) vulnerability affecting the Tab My Content WordPress plugin developed by patrice. The flaw stems from improper neutralization of user-supplied input during web page generation [CWE-79]. Attackers can craft malicious URLs that, when followed by an authenticated or unauthenticated victim, execute arbitrary JavaScript in the victim's browser session. The vulnerability affects all plugin versions up to and including 1.0.0. Successful exploitation can lead to session hijacking, credential theft, and unauthorized actions performed under the victim's privileges within the WordPress site.
Critical Impact
Reflected XSS enables attackers to execute arbitrary scripts in a victim's browser, potentially compromising administrator sessions and the WordPress site's integrity.
Affected Products
- Tab My Content plugin (tab-my-content) for WordPress
- All versions from n/a through 1.0.0
- WordPress sites with the plugin installed and active

Technical Details for CVE-2025-23601
Vulnerability Analysis
The vulnerability resides in the Tab My Content plugin's request handling logic, where input parameters are reflected into HTML output without adequate sanitization or output encoding. When a victim clicks a crafted link, the unescaped payload is rendered inside the response page, causing the browser to execute attacker-controlled JavaScript in the context of the WordPress origin.
Reflected XSS in a WordPress plugin context is particularly impactful because the same-origin trust extends across the entire site. Scripts executed via this flaw can interact with the WordPress REST API, exfiltrate session cookies that lack HttpOnly, manipulate the DOM of administrative pages, and submit privileged form requests. The CVSS vector indicates that exploitation requires user interaction and produces a scope change, reflecting the impact crossing security boundaries when an administrator is targeted.
Root Cause
The root cause is missing output encoding when reflecting request parameters into HTML responses. The plugin fails to apply WordPress sanitization helpers such as esc_html(), esc_attr(), or wp_kses() before placing input into the rendered page. As a result, HTML and JavaScript metacharacters supplied by an attacker remain intact in the server response.
Attack Vector
Exploitation is performed remotely over the network and requires user interaction. An attacker hosts or distributes a crafted URL targeting the vulnerable plugin endpoint with a JavaScript payload embedded in a reflected parameter. The victim is lured through phishing, social engineering, or malicious referrers. When the URL is loaded, the payload executes in the victim's authenticated browser session. No prior authentication is required for the attacker to weaponize the link.

Detection Methods for CVE-2025-23601
Indicators of Compromise
- Inbound HTTP requests to Tab My Content plugin endpoints containing <script>, javascript:, onerror=, or onload= patterns in query parameters.
- Unexpected outbound requests from administrator browsers to attacker-controlled domains immediately after visiting plugin URLs.
- WordPress audit logs showing privileged actions originating from administrators who recently followed an external link.
Detection Strategies
- Inspect web server access logs for URL parameters containing URL-encoded HTML or JavaScript payloads targeting tab-my-content paths.
- Deploy a Web Application Firewall (WAF) ruleset for reflected XSS that inspects query strings and form fields.
- Correlate referrer headers with subsequent administrative actions to identify suspicious click-through sequences.
Monitoring Recommendations
- Enable Content Security Policy (CSP) reporting to capture inline script execution attempts on WordPress pages.
- Monitor WordPress user activity for anomalous role changes, plugin installations, or content modifications following XSS-pattern requests.
- Aggregate web logs into a centralized analytics platform to baseline plugin parameter usage and alert on deviations.
How to Mitigate CVE-2025-23601
Immediate Actions Required
- Deactivate and remove the Tab My Content plugin until a patched version becomes available, as version 1.0.0 and earlier remain vulnerable.
- Apply WAF signatures that block reflected XSS payloads in query parameters targeting the plugin's endpoints.
- Force re-authentication of administrator accounts and rotate session cookies if exploitation is suspected.
Patch Information
No vendor-supplied fix has been documented in the NVD entry at the time of publication. The vulnerability affects Tab My Content versions through 1.0.0. Site operators should monitor the Patchstack advisory for patch availability and replace the plugin with a maintained alternative if a fix is not released.
Workarounds
- Restrict access to WordPress administrative paths via IP allow-listing or VPN to reduce the attack surface for targeted phishing.
- Configure a strict Content Security Policy that disallows inline scripts and untrusted script sources.
- Ensure session cookies are issued with HttpOnly and Secure attributes to limit cookie theft via JavaScript.
# Example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate tab-my-content
wp plugin delete tab-my-content
