A remote attacker could possibly use this issue to execute scripts in directories not directly reachable by any URL, or cause a denial of service. Some environments may require using the new UnsafeAllow3F flag to handle unsafe substitutions. (CVE-2024-38474, CVE-2024-38475, CVE-2024-39573)

Orange Tsai discovered that the Apache HTTP Server incorrectly handled certain response headers. A remote attacker could possibly use this issue to obtain sensitive information, execute local scripts, or perform SSRF attacks. (CVE-2024-38476)
