Cleantalk · Cleantalk-Spam-Protect · CVE-2019-17515
**Name of the Vulnerable Software and Affected Versions**
cleantalk-spam-protect plugin versions prior to 5.127.4
**Description**
The issue allows an attacker to execute arbitrary HTML and JavaScript code via the `from` or `till` parameter. This is possible when the Administrator is logged in and a reflected attack may execute upon a click on a malicious URL. The components affected are inc/cleantalk-users.php and inc/cleantalk-comments.php.
**Recommendations**
For versions prior to 5.127.4, update to version 5.127.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the inc/cleantalk-users.php and inc/cleantalk-comments.php components to minimize the risk of exploitation. Avoid using the `from` or `till` parameter in affected URLs until the issue is resolved.
