Vulnerability Overview

The Simple Post Notes plugin for WordPress is vulnerable to subscriber+ Stored Cross-Site Scripting via the 'spnote' parameter saved via the save_bulkedit_note() function which gets called through the wp_ajax_spnote_save_bulk_edit AJAX action. This affects versions up to 1.7.6, and version 1.7.6 is still vulnerable to unauthorized post note changes by subscriber level users due to a missing capability check on the spnote_save_bulk_edit action.

Technical Analysis

REMEDIATION: Update to version 1.7.6, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
