description

10Web Booster versions through 2.34.10 allow unauthenticated file uploads. An attacker who obtains an exposed REST nonce after a bulk optimization task pauses may upload executable content and potentially execute code on the site.

mitigation

Disable 10Web Booster on affected sites until the vendor releases an update. If it cannot be disabled immediately, restrict public access where feasible and monitor wp-content/uploads/ for unexpected files.
