## In brief

- CVE-2026-119618 is a critical flaw in mod_http2's assign_headers() function in Apache HTTP Server, described as heap corruption leading to remote code execution.
- The sources list affected versions as Apache HTTP Server 2.4.55 through 2.4.70.
- Wiz reports that 64% of cloud environments have resources vulnerable to the flaw.
