| High | CVE-2026-35414 | OpenSSH before 10.3 mishandles the authorized_keys principals option in uncommon scenarios involving a principals list in conjunction with a Certificate Authority that makes certain use of comma characters. | 8.1 | 0.0022 | None reported |
| High | CVE-2026-73282 | In ssh in OpenSSH before 10.5, a use-after-free for realloc data can occur if a certain pair of remote-forwarding operations are concurrent. | 7.5 | 0.0016 | None reported |
