What the vulnerability does
The Brandfolder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘id’ parameter in all versions up to, and including, 5.0.19 due to insufficient input sanitization and output escaping. 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
Brandfolder versions up to 5.0.19 contain a stored cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. When other users view affected content, the injected code executes in their browser with the same permissions as the victim. The vulnerability affects the integrity and confidentiality of user sessions across the platform.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and steal their session data or perform actions on their behalf.
Potential impact on your site
Users' accounts and data are at risk of compromise; attackers can impersonate legitimate users and access sensitive digital assets.
Conditions required to exploit
Attacker must have a valid Brandfolder account with low-level privileges; no user interaction required from victims.
