WordPress Plugin WP Email Template is prone to an HTML injection vulnerability because it fails to properly sanitize user-supplied input. Attacker supplied HTML and script code would run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or control how the site is rendered to the user; other attacks are also possible. WordPress Plugin WP Email Template version 2.2.10 is vulnerable; prior versions may also be affected.
