CVE-2025-58248 Overview
CVE-2025-58248 is a stored cross-site scripting (XSS) vulnerability in the codefish Pinterest Pinboard Widget plugin for WordPress. The flaw affects all versions of pinterest-pinboard-widget up to and including 1.0.7. An authenticated attacker with low privileges can inject persistent JavaScript payloads that execute in the browser of any user who views the affected page. The vulnerability is categorized under [CWE-79], improper neutralization of input during web page generation.
Critical Impact
Stored XSS payloads persist in the WordPress database and execute against site visitors and administrators, enabling session theft, forced actions, and further site compromise.
Affected Products
- codefish Pinterest Pinboard Widget plugin for WordPress
- All versions from n/a through 1.0.7
- WordPress sites with the vulnerable plugin activated

Technical Details for CVE-2025-58248
Vulnerability Analysis
The Pinterest Pinboard Widget plugin fails to properly neutralize user-supplied input before rendering it in WordPress pages. An authenticated user with access to the widget configuration can supply crafted input containing HTML or JavaScript. The plugin stores this payload in the database and returns it unescaped in generated markup. When any visitor loads a page rendering the widget, the browser parses and executes the attacker-controlled script.
The attack requires user interaction and low privileges, and the scope changes because injected scripts run in the trust context of the WordPress site. Successful exploitation can compromise administrator sessions, redirect visitors, mine credentials through injected forms, or chain into plugin and theme abuse for full site takeover. Refer to the Patchstack XSS Vulnerability Report for the coordinated disclosure record.
Root Cause
The plugin does not apply WordPress escaping functions such as esc_html(), esc_attr(), or wp_kses() to widget input before persistence and output. Missing output encoding at render time allows arbitrary markup to be treated as executable content by the browser.
Attack Vector
An authenticated contributor or editor supplies a payload through the widget's configuration fields. The malicious content is stored in the WordPress options or post metadata. Every subsequent request rendering the widget delivers the payload to visitors, achieving stored XSS with cross-scope impact.

Detection Methods for CVE-2025-58248
Indicators of Compromise
- Unexpected <script> tags, on*= event handlers, or javascript: URIs stored in WordPress wp_options or post metadata associated with the Pinterest Pinboard Widget.
- Outbound requests from visitor browsers to attacker-controlled domains after loading pages that render the widget.
- Newly created WordPress administrator accounts or unexpected changes to user roles following widget configuration edits.
Detection Strategies
- Query the WordPress database for widget option values containing HTML tags, script fragments, or encoded JavaScript payloads.
- Review web server access logs for POST requests to wp-admin/widgets.php or admin-ajax.php correlated with low-privilege accounts.
- Inspect rendered pages using a headless browser and flag unexpected script execution or DOM modification originating from widget output.
Monitoring Recommendations
- Enable a Web Application Firewall (WAF) with XSS signatures tuned for WordPress plugin input.
- Monitor plugin installation and update events, and alert on activation of pinterest-pinboard-widget versions at or below 1.0.7.
- Track authentication events for contributor and editor accounts, especially widget configuration changes outside normal working hours.
How to Mitigate CVE-2025-58248
Immediate Actions Required
- Deactivate and remove the Pinterest Pinboard Widget plugin if no patched release is available for your installation.
- Audit wp_options and widget-related database tables for stored payloads and remove any injected markup.
- Rotate credentials for WordPress administrators and enforce multi-factor authentication for all privileged accounts.
Patch Information
No fixed version is identified in the NVD record at the time of publication. The advisory lists all versions through 1.0.7 as vulnerable. Consult the Patchstack XSS Vulnerability Report for updated patch status and vendor guidance.
Workarounds
- Restrict widget configuration capabilities to trusted administrators by adjusting role permissions.
- Deploy a Content Security Policy (CSP) that disallows inline scripts and restricts script sources to trusted origins.
- Place the site behind a WAF configured to inspect and block XSS payloads in widget configuration requests.
# Example: remove the vulnerable plugin via WP-CLI
wp plugin deactivate pinterest-pinboard-widget
wp plugin delete pinterest-pinboard-widget
