PYSEC-2026-3834 ESPHome Device Builder Dashboard: Unauthenticated dashboard access via the HA add-on ingress site bound to all interfaces

Summary On the Home Assistant add-on, the dashboard serves a trusted ingress site that skips authentication because the supervisor authenticates the request upstream. That site was binding 0.0.0.0. The add-on runs in host network mode for mDNS, so binding all interfaces also bound the host's LAN...

PYSEC-2026-3809 asyncssh has an incomplete fix for CVE-2026-45309 — AuthorizedKeysFile %u still escapes the intended directory via a leading ~ (and weakly via ${ENV}) username substitution

Incomplete fix for CVE-2026-45309 GHSA-g794-3fmp-753h. The 2.23.0 guard that sanitises the SSH username before %u substitution in AuthorizedKeysFile blocks /, \ and .., but does not block a leading or $ENV, both of which are re-introduced by later expansion and reach the file open — defeating the...
