  • OpenSSH: OpenSSH: Security bypass via mishandling of authorized_keys principals option (CVE-2026-35414)

  • OpenSSH: OpenSSH: Information disclosure due to unintended cryptographic algorithm usage (CVE-2026-35387)

  • OpenSSH: OpenSSH: Low integrity impact from unconfirmed proxy-mode multiplexing sessions (CVE-2026-35388)

  • OpenSSH: OpenSSH: Arbitrary command execution via shell metacharacters in username (CVE-2026-35386)
