What the vulnerability does
The Social Post Embed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Threads embed handler in all versions up to, and including, 2.0.1. This is due to insufficient input sanitization and output escaping on the user-supplied URL. 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
Social Post Embed versions 2.0.1 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning the impact can extend beyond the vulnerable component itself. Site administrators should update to a version newer than 2.0.1 to remediate this issue.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and affect other site components.
Potential impact on your site
Authenticated users can inject scripts affecting other users and potentially compromise site integrity or steal data.
Conditions required to exploit
Attacker must have a low-privilege account (e.g., subscriber or contributor role) on the site.
