CVE-2023-49844Network attack vector

Admin-forced benchmark execution via missing nonce validation

Published Dec 18, 2023 · Updated Apr 28, 2026

CSRF in Kevin Ohashi WPPerformanceTester 2.0.0 and earlier allows remote attackers to make an administrator run a benchmark. The settingsPage handler trusts a performTest POST flag and starts test_benchmark and test_wordpress without validating a request nonce. Exploitation requires a logged-in administrator with manage_options to submit the forged request, causing unrequested CPU and database workload.
