Improper Authorization

The CreateSubAgent RPC is vulnerable to improper authorization. The vulnerability is due to the failure to validate the requested app sharing level against the template's maximum allowed sharing level before persisting workspace apps, which allows a workspace owner to exceed the...

PT-2026-56249

Name of the Vulnerable Software and Affected Versions Dashy versions prior to 4.3.7 Description The workspace view fails to validate the scheme of the URL query parameter before assigning it to an iframe source. This allows an attacker to execute JavaScript on the Dashy origin by tricking a...

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'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...

Origin Validation Error

Overview Affected versions of this package are vulnerable to Origin Validation Error via the CORS origin validation process. An attacker can gain unauthorized access to sensitive data by crafting a subdomain that encodes their own workspace UUID and a victim's username, then tricking an...

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...
