Today’s macOS updates fix security gap involving eMudhra certificates

AI-summarised brief · reviewed before publication

Apple released macOS updates that close a security gap involving compromised eMudhra certificates. Earlier this year Mozilla disclosed that private keys for eight eMudhra intermediate CAs had been stolen, allowing attackers to forge certificates and spoof websites. Apple responded by automatically blocking the certificates in Safari, Mail and other system frameworks on Oct. 19 and Oct. 23, but command‑line tools such as curl and git remained vulnerable. Today’s patches – macOS 27.2.1, 26.7.3 and 15.8.3 – extend the block to those tools and remove five root CAs from /etc/ssl/cert.pem, including three additional eMudhra roots. The updates also provide administrators with the SHA‑256 fingerprints of the 12 affected certificates and continue to offer manual remediation guidance for systems that cannot install the update today.

💡 Why It Matters

  • · Sealing the loophole in command‑line utilities stops attackers from leveraging forged eMudhra certificates in automated scripts and development pipelines.
