## Apache HTTP Server: heap corruption and RCE
Severity: unknown. Patch status: fix status unknown.
Affected: Apache Software Foundation Apache HTTP Server
Ids: CVE-2026-119618

Apache HTTP Server's mod_http2 has a concurrent execution vulnerability that can lead to RCE.

## Steps
1. This touches infrastructure (apache). Look in terraform, ansible, cloud-init, Dockerfiles and docs for the product and version we run. If it isn't in the repo, say so and list what a human should check on the box.
2. Apache HTTP Server 2.4.x: the CVE record names no fix; check the vendor advisory before assuming there is none. Until one ships: restrict network access to it.

## Fix by release line
| Line | State | Fix | Until then |
|---|---|---|---|
| Apache HTTP Server 2.4.x | not named in the CVE record | check the vendor advisory: https://httpd.apache.org/security/vulnerabilities_24.html | restrict network access to it |

## Report
A table: file, product or package, version in use, affected yes/no, exact fix. Then anything a human has to check outside the repo.

If you have the pwned.coffee MCP server (https://pwned.coffee/mcp), call lookup_cve("CVE-2026-119618") for the latest, and check_repo with this repo's lockfiles, Dockerfiles and workflows for a full receipt.
