Short explanation

CVE-2026-108014 is a critical vulnerability stemming from compromised private keys of eight eMudhra intermediate CA certificates, impacting certificate trust for outbound network request features in HCL Domino Server [S0]. An unauthenticated network attacker can spoof server certificates to execute a man-in-the-middle (MITM) attack, enabling them to intercept or modify outbound TLS connection contents [S0].

Why does it matter?

This critical vulnerability compromises the integrity and confidentiality of external network connections, allowing attackers to manipulate TLS traffic [S0].

What should be done?

  • Follow official vendor advisories [S0]
  • Review vendor guidance for patch status updates [S0]
