Name of the Vulnerable Software and Affected Versions MailArchiver plugin for WordPress versions up to, and including, 2.10.1

Description The issue is related to Stored Cross-Site Scripting via an email subject 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, 2.10.1, update to a version later than 2.10.1 to resolve the issue. As a temporary workaround, consider restricting access to email subjects to minimize the risk of exploitation.
