What is CVE-2011-10033?
CVE-2011-10033 is a critical code injection vulnerability in is-human WordPress Plugin, published on 15 Oct 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The WordPress plugin is-human <= v1.4.2 contains an eval injection vulnerability in /is-human/engine.php that can be triggered via the 'type' parameter when the 'action' parameter is set to 'log-reset'. The root cause is unsafe use of eval() on user-controlled input, which can lead to execution of attacker-supplied PHP and OS commands. This may result in arbitrary code execution as the webserver user, site compromise, or data exfiltration. The is-human plugin was made defunct in June 2008 and is no longer available for download. This vulnerability was exploited in the wild in March 2012.
