CVE-2025-23754 Overview
CVE-2025-23754 is a reflected cross-site scripting (XSS) vulnerability in the Ulrich Sossou The Loops WordPress plugin. The flaw affects all plugin versions up to and including 1.0.2. It stems from improper neutralization of user input during web page generation [CWE-79]. Attackers can craft malicious URLs that execute arbitrary JavaScript in the victim's browser when clicked. The issue is tracked under the Common Weakness Enumeration as [CWE-79].
Critical Impact
Successful exploitation enables session hijacking, credential theft, and unauthorized actions performed in the context of an authenticated WordPress user, including administrators.
Affected Products
- Ulrich Sossou The Loops WordPress plugin versions up to and including 1.0.2
- WordPress sites with the-loops plugin installed and activated
- All deployments of the plugin without an applied vendor fix

Technical Details for CVE-2025-23754
Vulnerability Analysis
The vulnerability is a reflected XSS issue in The Loops plugin for WordPress. User-supplied input is returned in HTTP responses without proper sanitization or output encoding. An attacker can place JavaScript payloads in a request parameter that the plugin reflects directly into the generated HTML page.
When a victim follows a crafted link, the injected script executes within the origin of the vulnerable WordPress site. This grants the attacker access to cookies, session tokens, and any sensitive content accessible to the victim's browser. The CWE-79 classification confirms the root cause as improper neutralization of input during web page generation.
The vulnerability requires user interaction, but successful exploitation has a scope change because the executed script operates in the browser context of the target site. This can affect users beyond the immediate vulnerable component, including site administrators.
Root Cause
The plugin fails to apply WordPress sanitization functions such as esc_html(), esc_attr(), or sanitize_text_field() to request-derived data before rendering it. Output encoding is missing on the reflection path, allowing HTML and script tokens to be interpreted by the browser as active content.
Attack Vector
The attack is network-based and requires no authentication. An adversary delivers a malicious URL containing an XSS payload through phishing emails, forum posts, or malicious advertisements. When the target user, typically a logged-in WordPress administrator or editor, clicks the link, the payload executes in the site's origin. The attacker can then exfiltrate session cookies, perform CSRF actions, or pivot to administrative functions.

Detection Methods for CVE-2025-23754
Indicators of Compromise
- HTTP requests to the-loops plugin endpoints containing <script>, javascript:, onerror=, or onload= tokens in query parameters
- Outbound browser requests to attacker-controlled domains immediately following access to The Loops plugin pages
- WordPress admin sessions originating from unfamiliar IP addresses shortly after a suspicious link was clicked
- Web server logs showing URL-encoded payloads such as %3Cscript%3E targeting plugin parameters
Detection Strategies
- Inspect WordPress access logs for query strings containing HTML or JavaScript syntax directed at the-loops plugin URLs
- Deploy a web application firewall (WAF) rule set that flags reflected XSS patterns in request parameters
- Monitor browser Content Security Policy (CSP) violation reports for inline script execution on pages rendered by the plugin
Monitoring Recommendations
- Enable verbose logging on the WordPress installation and forward logs to a centralized analytics platform for query parameter inspection
- Alert on creation of new administrator accounts or unexpected privilege changes following suspicious request activity
- Track referrers and user-agent strings that correlate with phishing campaigns targeting site administrators
How to Mitigate CVE-2025-23754
Immediate Actions Required
- Disable or remove the the-loops plugin from all WordPress installations until a patched version is confirmed and installed
- Invalidate active administrator sessions and force password resets for privileged WordPress accounts
- Audit recently created users, plugin changes, and theme modifications for signs of post-exploitation activity
Patch Information
The Patchstack advisory lists the vulnerability as affecting The Loops plugin versions up to and including 1.0.2. No fixed version is identified in the available CVE data at this time. Monitor the Patchstack XSS Vulnerability Report and the plugin's WordPress.org page for an official patched release.
Workarounds
- Deploy WAF rules that block requests containing common XSS payload signatures targeting the-loops plugin endpoints
- Apply a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins
- Train administrators to avoid clicking unsolicited links and to access the WordPress admin interface only from trusted networks
# Configuration example: temporarily deactivate the plugin via WP-CLI
wp plugin deactivate the-loops
wp plugin status the-loops
