CVE-2025-58867 Overview
CVE-2025-58867 is a stored cross-site scripting (XSS) vulnerability in the Remi Corson Easy Download Media Counter plugin for WordPress. The flaw affects all plugin versions up to and including 1.2. It stems from improper neutralization of user-supplied input during web page generation, classified as [CWE-79]. An authenticated attacker with low privileges can inject persistent JavaScript payloads that execute in the browser of any user viewing the affected page. Successful exploitation requires user interaction and can result in session theft, forced administrative actions, or redirection to attacker-controlled resources.
Critical Impact
Attackers with low-privilege authenticated access can inject persistent JavaScript that executes across administrative sessions, enabling account takeover and pivoting through the WordPress site.
Affected Products
- Remi Corson Easy Download Media Counter plugin for WordPress
- All versions from initial release through 1.2
- WordPress sites with the easy-download-media-counter plugin installed and activated

Technical Details for CVE-2025-58867
Vulnerability Analysis
The Easy Download Media Counter plugin fails to sanitize input before rendering it back into WordPress-generated pages. Because the payload is persisted server-side, the injected script runs each time a victim loads the affected view. The stored nature of the flaw removes the need for social engineering beyond a single visit to a plugin-controlled page.
The attack scope changes when exploited, meaning the injected script can affect resources beyond the vulnerable component itself. Impact extends to confidentiality, integrity, and availability of the browser session. Typical outcomes include cookie exfiltration, cross-site request forgery against authenticated endpoints, and unauthorized modification of plugin data.
Root Cause
The plugin accepts user-controlled values through its administrative interfaces and stores them without HTML encoding or contextual output escaping. When WordPress later renders these values inside plugin views, the browser interprets attacker-supplied markup as executable script. WordPress provides sanitization primitives such as sanitize_text_field() and esc_html() that were not applied at the appropriate output boundaries.
Attack Vector
Exploitation requires an authenticated account with contributor-level privileges or higher and interaction from a second user, typically an administrator. The attacker submits a malicious payload through a plugin field that lacks output escaping. The payload is stored in the WordPress database and executed when a privileged user opens the corresponding admin page or public-facing counter view.
The vulnerability is described in prose only; no verified proof-of-concept code has been published. For technical indicators, see the Patchstack XSS Vulnerability Report.
Detection Methods for CVE-2025-58867
Indicators of Compromise
- Unexpected <script>, <iframe>, or event-handler attributes stored in WordPress post metadata or plugin options tables
- Outbound browser requests from /wp-admin/ sessions to unfamiliar domains shortly after loading Easy Download Media Counter pages
- New or modified WordPress administrator accounts created without a corresponding audit trail
Detection Strategies
- Query the wp_options and plugin-specific tables for values containing HTML tags or JavaScript URI schemes such as javascript:
- Deploy a web application firewall rule that flags requests to plugin endpoints containing script tags or encoded payloads
- Review WordPress activity logs for unusual edits to plugin configuration by low-privilege users
Monitoring Recommendations
- Enable Content Security Policy (CSP) reporting to capture blocked inline script executions on WordPress admin pages
- Alert on modifications to the easy-download-media-counter plugin files or database rows outside of update windows
- Correlate authenticated session events with browser network telemetry to detect stored XSS activation
How to Mitigate CVE-2025-58867
Immediate Actions Required
- Deactivate and remove the Easy Download Media Counter plugin until a patched version is confirmed available
- Audit WordPress user accounts and rotate credentials for administrators and editors who accessed affected pages
- Inspect plugin database entries for stored payloads and remove any injected markup
Patch Information
At the time of publication, no fixed version has been identified. The vulnerability affects all releases through 1.2. Monitor the Patchstack advisory and the WordPress plugin repository for a security release.
Workarounds
- Restrict access to plugin administration pages using role-based access control until a patch ships
- Deploy a WAF signature that blocks script tags and JavaScript URI schemes on plugin-specific request parameters
- Enforce a strict Content Security Policy that disallows inline scripts on WordPress administrative routes
# Configuration example: remove the vulnerable plugin via WP-CLI
wp plugin deactivate easy-download-media-counter
wp plugin uninstall easy-download-media-counter
# Verify no residual plugin options remain
wp option list --search='easy_download_media_counter*'
