📅 6 May 2026 at 19:22 UTC📰 CIS AdvisoriesView original source ↗

A vulnerability has been discovered in Apache HTTP Server with the HTTP/2 protocol that could allow for remote code execution. Apache is a free, open-source web server software that enables the delivery of web content over the internet. Successful exploitation could result in denial of service, crashing worker processes with minimal effort. In certain setups, especially those using APR with mmap (common on Debian systems and official Docker images), it may also be exploited for remote code execution.
