A critical double-free vulnerability (CVE-2026-23918) in Apache HTTP Server 2.4.66's HTTP/2 handling allows specially crafted "early reset" frames to cause crashes or potentially enable remote code execution; Apache released a patch in version 2.4.67 on May 4, 2026. Organizations are advised to upgrade immediately, consider disabling HTTP/2 until patched, and implement monitoring and defense-in-depth controls to mitigate exploitation risk.
