A critical security vulnerability has been identified in Apache HTTP Server that could allow attackers to execute remote code (RCE). This issue affects HTTP/2 implementation and requires immediate attention from server administrators.
Apache Security Alert – RCE Vulnerability (2026)
This vulnerability is classified as high severity and may impact public-facing servers if not patched promptly.
What Is the Problem?
The issue originates from Apache’s HTTP/2 handling, where a memory corruption (double-free) condition can occur during stream processing. This may allow attackers to manipulate execution flow.
Key Risks:
Remote Code Execution: Attackers may execute malicious code on the server.
Memory Corruption: System instability and unexpected behavior.
High Exposure: Especially dangerous for public-facing hosting servers.
Affected Versions
Apache HTTP Server version 2.4.66 and possibly earlier versions are affected.
Recommended Solution
Upgrade Apache to the latest stable version immediately to mitigate the vulnerability.
Update Command (EasyApache / AlmaLinux / RHEL):
dnf -y update ea-apache*
Ubuntu-based systems:
apt updateapt install --only-upgrade apache2
Verify Update
httpd -v
Ensure your server reports the updated version.
Temporary Mitigation
Disable HTTP/2: Reduce exposure if immediate patching is not possible.
Audit Modules: Disable unused modules to reduce attack surface.
Secure Configuration: Review server permissions and access rules.
