| Titolo | ericc-ch copilot-api 0.7.0 DNS Rebinding Attack |
|---|
| Descrizione | The copilot-api HTTP server does not perform any validation on the Host header of incoming requests, allowing remote attackers to launch DNS rebinding attacks. An attacker can host a malicious web page that, after the initial DNS lookup, resolves to the victim’s localhost:4141, thereby bypassing the browser’s same-origin policy. Once the rebinding is successful, the attacker’s JavaScript can read responses from all copilot-api endpoints—including the /token endpoint, which returns the Copilot Bearer token in plaintext—and exfiltrate this information to a server controlled by the attacker. |
