What the vulnerability does
The WP-OAuth plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'error_description' parameter in all versions up to, and including, 0.4.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
WP-OAuth versions 0.4.1 and earlier contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. The vulnerability requires user interaction—victims must visit a crafted link or page. The impact extends beyond the vulnerable component, potentially affecting multiple users or site functionality.
What an attacker can do
Inject malicious JavaScript that runs in other users' browsers when they visit a crafted page.
Potential impact on your site
Site visitors could have their sessions hijacked, credentials stolen, or be redirected to malicious sites.
Conditions required to exploit
No authentication required. Victim must click a malicious link or visit an attacker-controlled page.
