Apache fixes critical HTTP/2 remote code execution flaw in version 2.4.71
A critical vulnerability, CVE-2026-119618, affects Apache HTTP Server versions 2.4.55 through 2.4.70 when the HTTP/2 module is enabled, potentially letting unauthenticated attackers remotely execute code. The Apache project's advisory says the flaw is fixed in version 2.4.71, which also patches an important mod_md crash bug and a low-severity stack overwrite in mod_vhost_alias. Standalone builds of the module (mod_h2) versions 2.0.8 through 2.0.42 are also affected.
