Vulnerability Overview
The Copy Anything to Clipboard for WordPress – Copy Button, Copy Text & Copy Code plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to 5.5.5. This is 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.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-79: Improper Neutralization of Input During Web Page Generation
Reaching this weakness in Copy Anything to Clipboard for WordPress < 5.5.5 takes an account at Contributor level or above. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Copy Anything to Clipboard for WordPress the fix is 5.5.5: builds < 5.5.5 are affected, anything from 5.5.5 onward is not.
Remediation
Update to version 5.5.5, or a newer patched version
How does WordSec protect against this?
An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Copy Anything to Clipboard for WordPress 5.5.5 closes this, and updating the plugin is the step that ends it.
