Description
WordPress Plugin Subscribe to Comments is prone to multiple cross-site scripting vulnerabilities because the application fails to sufficiently sanitize user-supplied data. Attacker-supplied HTML or JavaScript code could run in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials; other attacks are also possible. WordPress Plugin Subscribe to Comments versions prior to 2.0.8 are vulnerable.
Remediation
Update to plugin version 2.1 or latest
