What the vulnerability does
The WPlyr Media Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '_wplyr_accent_color' parameter in all versions up to, and including, 1.3.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
WPlyr Media Block versions 1.3.0 and earlier contain a cross-site scripting vulnerability that allows high-privilege users to inject malicious scripts affecting other users or the site. The vulnerability requires high attack complexity and high privileges to exploit. Impact is limited to low-level confidentiality and integrity compromise.
What an attacker can do
Inject malicious scripts that execute in other users' browsers or affect site functionality.
Potential impact on your site
Administrators or editors with malicious intent could inject scripts affecting other users or site content.
Conditions required to exploit
