Name of the Vulnerable Software and Affected Versions The Newsletter, SMTP, Email marketing and Subscribe forms by Sendinblue WordPress plugin versions prior to 3.1.25

Description The issue is related to a Reflected Cross-Site Scripting problem. It occurs because the sib-statistics-date parameter is not properly escaped before being outputted back in an attribute. This allows for potential malicious script injection.
