CVE-2026-55430

Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2, the workspace app proxy resolves the target app from httpapi.RequestHost which prefers the X-Forwarded-Host header over the real Host header. No middleware...

CVE-2026-55430

Coder's workspace app (github.com/coder/coder) prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2 trusts X-Forwarded-Host for routing because no middleware strips it before routing and httpapi.RequestHost() prefers that header over Host. This enables cross-app data access when subdomain (wildca...
