If you can't patch immediately
Apply at least one of the following inline controls until you can deploy the patched build. None replace the upgrade.
Restrict exposure with nftables (Linux)
# Allow only trusted CIDR to reach the affected service ports
sudo nft add table inet filter 2>/dev/null || true
sudo nft 'add chain inet filter input { type filter hook input priority 0 ; }' 2>/dev/null || true
sudo nft 'add rule inet filter input tcp dport {80, 443} ip saddr != 10.0.0.0/8 drop'
sudo nft list ruleset
Block at the host firewall (Windows)
New-NetFirewallRule -DisplayName "Block-CVE-2026-28062" -Direction Inbound -Action Block -Protocol TCP -LocalPort 80,443 -RemoteAddress Any -Enabled True
Get-NetFirewallRule -DisplayName "Block-CVE-2026-28062"
Disable the affected service (Linux)
sudo systemctl stop happy-baby 2>/dev/null || true
sudo systemctl disable happy-baby 2>/dev/null || true
If the vendor advisory lists an official workaround, prefer that wording verbatim. If no workaround is published, the only safe remediation is the patch.
How to verify the fix worked
After upgrading, confirm the installed version matches the patched build and that no old library is still loaded by a long-running process.
# Linux
dpkg -s happy-baby 2>/dev/null | grep -i ^Version
rpm -q happy-baby 2>/dev/null || true
# Pid map check for old library handles
sudo lsof +c0 2>/dev/null | grep -i "DEL.*lib" || true
# Windows
Get-Package -Name "*Happy Baby*" | Select-Object Name, Version
Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 5
Expected: the reported version is at or above See vendor advisory. Restart the affected service (systemctl restart <service> on Linux, or restart the Windows service) so it loads the patched binary.
