Name of the Vulnerable Software and Affected Versions The Newsletter plugin for WordPress versions up to, and including, 8.3.4

Description The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts in pages via the np1 parameter, which will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 8.3.4, update to a version that addresses the insufficient input sanitization and output escaping issue to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the np1 parameter to minimize the risk of exploitation.
