Vulnerability Overview
The Compact WP Audio Player WordPress plugin before 1.9.7 does not escape some of its shortcodes attributes, which could allow users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Compact WP Audio Player <= 1.9.6 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Compact WP Audio Player the fix is 1.9.7: builds <= 1.9.6 are affected, anything from 1.9.7 onward is not.
Remediation
Update to version 1.9.7, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Compact WP Audio Player: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Compact WP Audio Player 1.9.7 closes this, and updating the plugin is the step that ends it.
