Type:
security
Severity:
Moderate
Release date:
2026-09-08 17:12:36 UTC
Description:
- CVE-2026-73283: make the authorized_keys restrict keyword apply to tunnel forwarding by rejecting tun/tap requests when auth_opts->restricted is set in server_request_tun(); backport upstream d322f2cc verbatim. The new term is inert until sshauthopt_merge() preserves restricted, which upstream does not yet do either -- see the patch header
