I reported this vulnerability through the official Apache HTTP Server security email on April 1, 2024, and received a fix along with a CVE number on July 1, 2024. You can check detailed information from there:
> https://httpd.apache.org/security/vulnerabilities_24.html

Impact

null pointer dereference in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows an attacker to crash the server via a malicious request.

Users are recommended to upgrade to version 2.4.60, which fixes this issue.
