CVE-2026-8894: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in vinaysankhyan iWR Tooltip
The iWR Tooltip plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `iwrtooltip` shortcode in versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping on user supplied attributes in the iwr_tooltip() shortcode handler — the `title` attribute is concatenated directly into an HTML attribute without esc_attr() or any other escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2026-8894 describes a stored cross-site scripting vulnerability in the iWR Tooltip plugin for WordPress. The issue arises because the plugin's iwr_tooltip() shortcode handler directly concatenates the user-supplied 'title' attribute into an HTML attribute without proper escaping functions such as esc_attr(). This allows authenticated users with contributor or higher privileges to inject arbitrary JavaScript code that executes in the context of users viewing the compromised pages. The vulnerability affects versions up to and including 1.0. No patch or official remediation has been documented.
Potential Impact
Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages, potentially leading to session hijacking, defacement, or other client-side attacks against users viewing the injected content. The vulnerability does not require user interaction beyond page viewing and does not impact availability. The CVSS score of 6.4 reflects a medium severity with low attack complexity and privileges required.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access and above to trusted users only. Consider disabling or removing the iWR Tooltip plugin if it is not essential. Monitor for plugin updates that address this vulnerability.
