What the vulnerability does
The WordPress Social Share Buttons plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 1.19. 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
Social Share Buttons versions 1.19 and earlier contain a cross-site scripting (XSS) vulnerability. An attacker can inject malicious scripts that execute in a visitor's browser when they view an affected page. The vulnerability requires user interaction—the victim must visit a crafted link or page. The attack can affect other users and potentially compromise site integrity.
What an attacker can do
Inject malicious JavaScript that runs in visitors' browsers and steals data or modifies page content.
Potential impact on your site
Visitors to your site could have their sessions hijacked, credentials stolen, or see altered content if they click a malicious link.
Conditions required to exploit
No authentication required. Victim must visit a page containing the malicious payload (user interaction required).
