Description
The All in One SEO plugin for WordPress is vulnerable to Sensitive Information Exposure via 'internalOptions' localized script data in versions up to, and including, 4.9.7 due to sensitive internal option data being passed to wp_localize_script() in post editor contexts without effective masking for low-privilege users. This makes it possible for authenticated attackers, with contributor-level access and above, to view configured API/OAuth tokens and license-related values from page source.
