Affected versions of this package are vulnerable to Permissive Cross-domain Policy with Untrusted Domains in the POST /agui endpoint due to the absence of authentication and the use of a hardcoded Access-Control-Allow-Origin: * header. An attacker can execute arbitrary agent actions and exfiltrate sensitive data by luring a victim to visit a malicious website, which then sends crafted cross-origin requests to a locally running server.
Note: This is only exploitable if the AGUI server is running locally and the victim visits an attacker-controlled website.
