Matrix Server Key Generation Vulnerability in Element Server Suite Community Edition

CVE-2026-24044

What is CVE-2026-24044?

The Element Server Suite Community Edition contains a vulnerability in its Helm Chart that utilizes an insecure method for generating Matrix server keys. If certain configuration settings are not properly disabled, attackers could potentially regenerate the same key pair, gaining the ability to impersonate the victim server. This poses risks to the confidentiality, integrity, and availability of communication within Matrix rooms involving the compromised server. Although prior conversations in end-to-end encrypted rooms remain secure, this vulnerability emphasizes the need for secure key generation practices. Users are advised to update to matrix-tools version 0.5.7 or later, included with ESS Community Helm Chart 25.12.1, to mitigate these risks.
