CVE-2026-55431

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, coder open app opens external workspace-app URLs without validating the scheme or host. When an external app URL contains the $SESSIONTOKEN placeholder the...

CVE-2026-55431

Coder prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2 is vulnerable to session-token leakage via coder open app for external workspace apps.

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...

Coder is vulnerable to command injection in the dotfiles registry module, exploitable via crafted dotfiles_uri values and the mode=auto workflow. Root cause: unsanitized user input interpolated into shell commands, enabling arbitrary code execution inside a provisioned workspace, especially when ...

CVE-2026-55434 Coder vulnerable to denial of service via unbounded request body in AI Bridge provider endpoints

Coder allows organizations to provision remote development environments via Terraform. Starting in version 2.33.0 and prior to versions 2.33.8 and 2.34.2, AI Bridge provider handlers read request bodies with io.ReadAll without a maximum size so an authenticated user with AI Bridge access could se...
