ShortPixel Image Optimizer <= 6.4.2 - Authenticated (Editor+) Arbitrary File Read via 'loadFile' Parameter
Source: NVD (National Vulnerability Database)
Vulnerability Description
The ShortPixel Image Optimizer plugin for WordPress is vulnerable to Arbitrary File Read via path traversal in the 'loadFile' parameter in all versions up to, and including, 6.4.2 due to insufficient path validation and sanitization in the 'loadLogFile' AJAX action.
