HIGHCVSS 7.8/10Actively ExploitedEPSS 65.00%

Last modified Jun 17, 2026

CVE-2019-0211 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected.. CISA has confirmed active exploitation in the wild. EPSS estimates a 65.00% chance of exploitation in the next 30 days.
