CVE-2025-47673 Overview
CVE-2025-47673 is a reflected cross-site scripting (XSS) vulnerability in the Arconix Shortcodes WordPress plugin developed by tychesoftwares. The flaw stems from improper neutralization of user-supplied input during web page generation [CWE-79]. Attackers can craft malicious URLs that inject JavaScript into pages rendered by the plugin. When a victim clicks the link, the script executes in the victim's browser context. The vulnerability affects all versions of Arconix Shortcodes from initial release through version 2.1.16.
Critical Impact
Successful exploitation allows attackers to execute arbitrary JavaScript in a victim's browser, enabling session hijacking, credential theft, and unauthorized actions on the affected WordPress site.
Affected Products
- Arconix Shortcodes WordPress plugin versions up to and including 2.1.16
- WordPress sites running the tychesoftwares Arconix Shortcodes plugin
- Any WordPress installation where the vulnerable plugin processes user-controlled input

Technical Details for CVE-2025-47673
Vulnerability Analysis
The vulnerability is a reflected XSS flaw classified under [CWE-79]. Arconix Shortcodes fails to sanitize or escape user-supplied input before reflecting it back in HTTP responses. An attacker crafts a URL containing JavaScript payloads in parameters processed by the plugin. The server includes that input in the rendered HTML without encoding special characters. The injected script then executes in the victim's browser under the origin of the WordPress site.
The attack requires user interaction, typically a victim clicking a malicious link. Because the scope changes when the payload executes, the attacker can affect resources beyond the vulnerable component. Stolen session cookies can be used to impersonate authenticated users, including administrators.
Root Cause
The root cause is missing output encoding and input validation in the plugin's shortcode handlers. Input received through query parameters or form fields is concatenated into HTML without applying WordPress sanitization functions such as esc_html(), esc_attr(), or wp_kses(). This allows raw HTML and <script> tags to reach the browser intact.
Attack Vector
The attack vector is network-based with low complexity and requires no authentication. An attacker delivers a crafted URL to a victim through phishing, malicious advertising, or social engineering. When the victim's browser loads the URL, the embedded payload runs within the WordPress site's origin. Refer to the Patchstack WordPress Vulnerability Report for technical details on the affected parameters.
Detection Methods for CVE-2025-47673
Indicators of Compromise
- HTTP requests containing URL-encoded <script> tags, javascript: URIs, or event handlers such as onerror= and onload= in query parameters processed by Arconix shortcodes
- Unexpected outbound requests from user browsers to attacker-controlled domains after visiting WordPress pages
- WordPress access logs showing referrers from external sites with suspicious query strings targeting plugin endpoints
Detection Strategies
- Inspect web server access logs for query parameters containing HTML special characters, encoded script tags, or known XSS payload patterns
- Deploy a web application firewall (WAF) with rules tuned to identify reflected XSS attempts against WordPress plugin endpoints
- Monitor browser-side Content Security Policy (CSP) violation reports for blocked inline script execution attempts
Monitoring Recommendations
- Centralize WordPress and web server logs into a SIEM and alert on payload signatures matching reflected XSS attempts
- Track plugin inventory across WordPress deployments to identify hosts running Arconix Shortcodes version 2.1.16 or earlier
- Review administrator session activity for anomalous logins, content changes, or new user creation following suspicious request patterns
How to Mitigate CVE-2025-47673
Immediate Actions Required
- Update Arconix Shortcodes to a version later than 2.1.16 once a patched release is available from tychesoftwares
- Deactivate and remove the plugin if no patched version is available and the functionality is not business-critical
- Audit administrator accounts and rotate session tokens and passwords if exploitation is suspected
Patch Information
No fixed version is identified in the published advisory at the time of writing. Monitor the Patchstack WordPress Vulnerability Report and the WordPress plugin repository for updates from tychesoftwares.
Workarounds
- Deploy a WAF rule set to block requests containing common XSS payloads targeting Arconix Shortcodes parameters
- Implement a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins
- Restrict access to pages using vulnerable shortcodes until a patch is applied
