Description

The Post SMTP Mailer/Email Log plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘input_tmp_dir’ parameter in versions up to, and including, 2.1.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
