Improper Access Control

Coder is vulnerable to Improper Access Control. The vulnerability is due to the tailnet coordinator validating an agent's Addresses but not its AllowedIPs, which allows an authenticated attacker to advertise unauthorized IP prefixes that are propagated to WireGuard peers, potentially enabling...

CVE-2026-55428 Coder: Route hijacking through lack of validation of agent-supplied AllowedIPs in tailnet coordinator

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 tailnet coordinator validates that an agent's Addresses derive from its authenticated UUID but applies no equivalent check to AllowedIPs. The coordinato...

CVE-2026-55428

CVE-2026-55428 (Coder) describes a route hijack risk in the tailnet coordinator where an agent’s AllowedIPs are not validated against the agent’s authenticated UUID, unlike the Addresses check. The coordinator forwards adversarially supplied AllowedIPs to WireGuard peers, potentially enabling an ...

GHSA-QRWJ-VH9X-GW5V Coder's workspace agent API insecure redirect handling allowed cross-agent file read and write

Summary agentConn.apiClient used the default redirect behavior of http.Client while its custom transport dialed the host from the request URL as long as the port was the workspace agent HTTP API port 4. Agent tailnet IPs are deterministic from agent UUIDs, so a malicious workspace agent could...

Coder: Route hijacking through lack of validation of agent-supplied AllowedIPs in tailnet coordinator

Summary The tailnet coordinator validates that an agent's Addresses derive from its authenticated UUID but applies no equivalent check to AllowedIPs. The coordinator forwards agent-supplied AllowedIPs verbatim to tunnel peers which install them into the WireGuard peer configuration. Impact A...

Incorrect Authorization

Overview Affected versions of this package are vulnerable to Incorrect Authorization in the AllowedIPs process. An attacker can intercept network traffic and serve spoofed content by supplying arbitrary AllowedIPs prefixes, allowing them to claim another agent's tailnet address. This is only...
