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...

Server-side Request Forgery (SSRF)

Overview Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the agentConn.apiClient process. An attacker can gain unauthorized access to sensitive files or execute arbitrary commands as another workspace user by redirecting API requests to a victim's agent,...

Coder's workspace app CORS origin check can be bypassed via UUID-based subdomain spoofing

Summary Coder's subdomain-based workspace app proxy allowed the same-owner CORS check to be bypassed. When a workspace-name subdomain segment parsed as a UUID, the workspace was resolved by ID without confirming the URL's username matched the real owner, while the CORS middleware trusted the...

GHSA-7QW2-F75V-62F7 Coder vulnerable to stored HTML injection via workspace agent logs in AgentLogLine component

Summary The AgentLogLine dashboard component instantiated ansi-to-html without escapeXML: true and inserted the result via dangerouslySetInnerHTML so HTML embedded in workspace agent log lines was rendered as live markup. Server-side sanitization did not neutralize HTML metacharacters. Note:...

GHSA-X9QQ-2QH5-8RXF Coder's sub-agent app registration bypasses template port-sharing policy enforcement

Summary The CreateSubAgent RPC did not validate a requested app sharing level against the template's MaxPortSharingLevel before persisting workspace apps, letting a workspace owner exceed the administrator's configured maximum. Note: Exploitation requires the ability to register sub-agent apps in...

GHSA-V54H-CP2W-9X4G Coder's session token leaked to arbitrary hosts via `coder open app` for external workspace apps

Summary coder open app opens external workspace-app URLs without validating the scheme or host. When an external app URL contains the $SESSIONTOKEN placeholder the CLI replaces it with the user's real session token before handing the URL to the OS open handler. Note: Practical exploitation requir...
