Product showcase: Sweet Virtual Patching stops HTTP2Shell while fixes catch up
HTTP2Shell (CVE-2026-111497), the critical Brotli bug first known as Node2Shell, is a remote code execution flaw in the compression library inside Node.js, Bun, Envoy, Python and more. AI found it: OpenAI’s agents turned it up in late September during a high-compute red-teaming campaign. Finding bugs is getting faster. Fixing them isn’t. HTTP2Shell shows why that gap matters, and how Sweet Virtual Patching protects running applications until the fixes land. A bad stream, a broken decoder …

HAProxy Community and HAProxy Enterprise are NOT vulnerable to the new HTTP2Shell vulnerability (CVE-2026-111497). But your backend applications might still be at risk.

You can use HAProxy to block the attack vector at the edge while you patch your fleet: www.haproxy.com/blog/haproxy...
HAProxy is not vulnerable to HTTP2Shell (CVE-2026-111497)
HAProxy is not vulnerable to Brotli CVEs (HTTP2Shell) because it doesn't provide Brotli decoding. However, it can help protect vulnerable backends by blocking potentially dangerous requests.

The fallout from both Php2Shell and Http2Shell (to use another example) was largely fuelled by not updating stuff, and I shudder to think of all the critical stuff that hasn't been updated.
If you have any influence at your workplace, NOW is the time to start pushing for updating and upgrading.

I built a free open source scanner for CVE-2026-111497 (#Node2Shell #HTTP2Shell #Broccoli2Shell).

It checks the Brotli code in binaries, not version numbers: finds copies in Node.js, Python, .NET, Bun and sees distro backports.
