GoKawiilApache 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.
GoKawiil's interpretation of the reporting above, not reported fact.
The vendor's advisory claims public research has shown a reliable exploit against default configurations with mod_http2 enabled, though it does not identify that research. Security firm Wiz later contradicted this, stating no exploit code exists and no in-the-wild exploitation has been reported, highlighting uncertainty about the real-world urgency of patching. Because HTTP/2 can be enabled per virtual host as well as server-wide, administrators may need to check multiple configuration points to confirm exposure.
- CVE-2026-119618 affects Apache HTTP Server 2.4.55-2.4.70 and standalone mod_h2 builds 2.0.8-2.0.42 when HTTP/2 is enabled
- Apache's advisory cites unnamed public research claiming a reliable exploit, but Wiz says no exploit or active attacks have been confirmed
- Version 2.4.71 fixes the flaw along with a mod_md crash bug and a low-severity mod_vhost_alias memory issue
