What the vulnerability does
01Description
The WordPress + Microsoft Office 365 / Azure AD | LOGIN plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'pintra' shortcode in all versions up to, and including, 27.2 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-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
02Summary
WPO365 Login plugin versions up to 27.2 contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts affecting other users on the site. The vulnerability has a changed scope, meaning the impact extends beyond the plugin itself. An attacker with low-level WordPress access can craft a payload that executes in other users' browsers, potentially stealing session data or performing actions on their behalf.
What an attacker can do
03Attacker Capabilities
