Name of the Vulnerable Software and Affected Versions The POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress plugin for WordPress versions up to, and including, 2.8.7

Description The issue is related to Stored Cross-Site Scripting via the device header due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 2.8.7, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the device header to minimize the risk of exploitation.
