Survey Maker < 5.1.9.5 - Missing Authorization to Unauthenticated Limited Option Update

Description

The Survey Maker plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the deactivate_plugin_option() function in all versions up to, and including, 5.1.9.4. This makes it possible for unauthenticated attackers to update the ays_survey_maker_upgrade_plugin option.
