Publicly Published February 21, 2023
Last Updated February 22, 2023


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.
