CVE-2025-58614: Tooltipy WordPress Plugin XSS Vulnerability

CVE-2025-58614 Overview

CVE-2025-58614 is a stored cross-site scripting (XSS) vulnerability in the Tooltipy (bluet-keywords-tooltip-generator) WordPress plugin by Jamel.Z. The flaw affects all plugin versions up to and including 5.5.6. An authenticated attacker with low privileges can inject persistent JavaScript payloads that execute in the browsers of users who view affected pages. Because the injected script runs in the site context, an attacker can hijack sessions, exfiltrate data, or perform actions on behalf of victims. The vulnerability maps to [CWE-79]: Improper Neutralization of Input During Web Page Generation.

Critical Impact
A low-privileged authenticated user can store malicious JavaScript that executes against site visitors and administrators, enabling session theft, content manipulation, and potential site takeover through follow-on privilege escalation.

Affected Products

Jamel.Z Tooltipy (bluet-keywords-tooltip-generator) WordPress plugin
All versions from initial release through 5.5.6
WordPress installations with the vulnerable plugin activated

Technical Details for CVE-2025-58614

Vulnerability Analysis

The Tooltipy plugin fails to properly neutralize user-supplied input before rendering it inside generated web pages. An authenticated user with contributor-level or similar privileges can submit crafted input through plugin fields, and the payload is stored in the WordPress database. When any user later loads a page that renders that stored data, the browser parses the injected script as executable HTML/JavaScript.

Stored XSS is more impactful than reflected XSS because it does not require the attacker to lure victims to a crafted link. The scope change indicator in the vulnerability metadata reflects that the injected script executes in the security context of the WordPress site, affecting resources beyond the vulnerable component itself.

Root Cause

The root cause is missing or insufficient output encoding and input sanitization in one or more plugin fields that accept keyword or tooltip content. WordPress provides sanitization helpers such as wp_kses_post(), esc_html(), and esc_attr(), but the vulnerable code path does not apply appropriate escaping before persisting or rendering data.

Attack Vector

Exploitation requires network access to the WordPress admin interface and a low-privileged authenticated account. User interaction is required, meaning a victim must load a page or admin view that renders the stored payload. The attacker submits JavaScript through the plugin's tooltip or keyword configuration inputs. Once stored, the payload triggers whenever the affected content is displayed, including in administrator dashboards where session cookies and nonces are accessible.

Detection Methods for CVE-2025-58614

Indicators of Compromise

Unexpected <script> tags, on* event handlers, or JavaScript URIs stored in plugin-managed WordPress database tables
Outbound requests from administrator sessions to unfamiliar external domains shortly after loading pages that render tooltip content
New administrator accounts, modified user roles, or unexpected plugin installations following contributor account activity
Browser console errors or content security policy violations on pages that display Tooltipy keywords

Detection Strategies

Audit the wp_posts, wp_postmeta, and plugin-specific tables for stored HTML containing script tags or encoded JavaScript payloads
Review WordPress access logs for POST requests to Tooltipy administration endpoints from low-privileged accounts
Monitor for anomalous DOM modifications and script execution on pages using the plugin

Monitoring Recommendations

Enable and review WordPress audit logs for content changes made by contributor or author roles
Deploy a web application firewall (WAF) with rules that flag script payloads submitted to plugin endpoints
Alert on privilege changes, plugin installs, and theme edits that occur outside change-management windows

How to Mitigate CVE-2025-58614

Immediate Actions Required

Update the Tooltipy plugin to a version newer than 5.5.6 once the vendor publishes a fix
Restrict contributor and author account creation and audit existing low-privileged accounts for legitimacy
Purge stored tooltip and keyword entries that contain HTML or script content pending remediation
Rotate administrator session cookies and reset passwords if suspicious tooltip content is identified

Patch Information

At the time of publication, refer to the Patchstack Vulnerability Disclosure for current patch status. If no fixed version is available, deactivate and remove the plugin until the vendor releases a security update.

Workarounds

Deactivate the Tooltipy plugin on affected WordPress sites until a patched version is installed
Enforce a strict Content Security Policy (CSP) that blocks inline scripts and untrusted script sources
Apply WAF virtual-patching rules that block script tags and JavaScript event handlers in requests targeting plugin endpoints
Limit the WordPress editor and contributor roles to trusted users only

bash

# Example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate bluet-keywords-tooltip-generator
wp plugin delete bluet-keywords-tooltip-generator
