Description
WordPress Plugin s2Member Pro 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 s2Member Pro version 111216 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 111220 or latest
