Advisory
Source description from Wordfence Intelligence.
The 10Web Booster – Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check within the settings import functionality in versions up to, and including, 2.13.44. This makes it possible for unauthenticated attackers to conduct cross-site scripting attacks by injecting arbitrary web scripts in the two_delay_custom_js setting that will execute whenever a user accesses an injected page.
