The CodePeople Post Map for Google Maps plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'cpm_point' Post Meta in all versions up to, and including, 1.2.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
