CVE-2025-62926 Overview
CVE-2025-62926 is a stored Cross-Site Scripting (XSS) vulnerability in the HappyDevs TempTool [Show Current Template Info] WordPress plugin, tracked under the current-template-name slug. The flaw affects all plugin versions up to and including 1.3.1. It stems from improper neutralization of input during web page generation, classified under [CWE-79].
An authenticated attacker with low privileges can inject persistent JavaScript payloads that execute in the browsers of other users who view the affected pages. Because the injected script executes within the trusted origin, attackers can hijack sessions, alter rendered content, or pivot to administrative actions when a privileged user is targeted.
Critical Impact
Stored XSS enables persistent script execution in the WordPress admin context, exposing site administrators to session hijacking and unauthorized configuration changes.
Affected Products
- HappyDevs TempTool [Show Current Template Info] plugin for WordPress
- All versions from initial release through 1.3.1
- WordPress sites with the current-template-name plugin slug installed

Technical Details for CVE-2025-62926
Vulnerability Analysis
The vulnerability resides in the TempTool plugin's handling of user-supplied input rendered back into WordPress-generated pages. Input passed to the plugin is stored without adequate sanitization or output encoding. When the affected page renders, the plugin emits the stored payload directly into the HTML response, allowing arbitrary JavaScript execution.
The scope change indicated by the vulnerability metrics reflects that injected scripts execute in a security context different from the vulnerable component. Exploitation requires authentication at a low privilege level and one instance of user interaction, such as an administrator viewing the impacted plugin interface.
Successful exploitation compromises the confidentiality, integrity, and availability of data accessible to the victim's browser session. Attackers commonly leverage stored XSS in WordPress to create rogue administrator accounts, exfiltrate authentication cookies, or inject supply-chain payloads into the site frontend.
Root Cause
The root cause is missing input neutralization on the current-template-name parameter within the TempTool plugin. The plugin fails to apply WordPress core sanitization functions such as sanitize_text_field() on input, and it omits output encoding via esc_html() or esc_attr() when rendering stored values.
Attack Vector
An authenticated user with contributor-level or comparable low privileges submits a crafted payload containing HTML or JavaScript through the vulnerable plugin input. The payload persists in the WordPress database. When another user, such as an administrator, loads a page that renders the stored value, the browser executes the attacker-controlled script within the site's origin.

Detection Methods for CVE-2025-62926
Indicators of Compromise
- Unexpected <script>, onerror, or onload attributes stored in WordPress post metadata or plugin option tables
- New administrator accounts created without an audit trail from a legitimate admin session
- Outbound requests from admin browsers to unfamiliar domains shortly after loading TempTool-managed pages
- Modified wp_options or theme files following administrator page views
Detection Strategies
- Inspect the WordPress database for HTML and JavaScript characters in fields associated with the current-template-name plugin
- Review web server access logs for POST requests to TempTool endpoints containing encoded script fragments
- Correlate WordPress user activity logs with unexpected privilege changes or plugin configuration edits
Monitoring Recommendations
- Deploy a web application firewall rule set that flags XSS payload signatures targeting WordPress plugin parameters
- Enable WordPress audit logging to record post edits, option changes, and user role modifications
- Monitor endpoint browsers of administrative users for anomalous outbound connections following CMS activity
How to Mitigate CVE-2025-62926
Immediate Actions Required
- Identify all WordPress installations running TempTool [Show Current Template Info] version 1.3.1 or earlier
- Deactivate and remove the plugin until a patched release is confirmed available from the vendor
- Rotate credentials and invalidate active sessions for any accounts that may have viewed injected content
- Audit administrator accounts and installed plugins for unauthorized changes
Patch Information
At the time of publication, the NVD entry does not list a fixed version. Monitor the Patchstack Vulnerability Report and the plugin's WordPress.org listing for updates beyond version 1.3.1. Apply the fixed release as soon as it is published.
Workarounds
- Restrict access to the WordPress admin dashboard to trusted IP ranges using server-level access controls
- Enforce a strict Content Security Policy (CSP) that disallows inline scripts on WordPress admin pages
- Limit low-privileged user roles from accessing plugin configuration areas where the injection surface exists
- Uninstall the plugin entirely if template inspection functionality is not required in production
# Configuration example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate current-template-name
wp plugin uninstall current-template-name
