What the vulnerability does
The WordPress GDPR plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'gdpr_firstname' and 'gdpr_lastname' parameters in all versions up to, and including, 2.0.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
The WordPress GDPR plugin through version 2.0.2 contains a stored cross-site scripting (XSS) vulnerability that allows unauthenticated attackers to inject malicious scripts into the site. Because the scope is changed, the injected code can affect other users and site functionality. No user interaction is required for the vulnerability to be triggered once the malicious payload is stored.
What an attacker can do
Inject malicious JavaScript that executes in other users' browsers and affects site functionality.
Potential impact on your site
Visitors and administrators may have their sessions hijacked, credentials stolen, or be redirected to malicious sites.
Conditions required to exploit
Network access only; no authentication or user interaction required.
