InPost Gallery <= 2.1.2 - Cross-Site Scripting
Strategic Overview
Vulnerability Overview
The InPost Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'admin_thumb_width' parameter in versions up to, and including, 2.1.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Technical Analysis
REMEDIATION: Update to version 2.1.2.1, 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.
