Titelericc-ch copilot-api 0.7.0 Cross-Origin Token Theft via Wildcard CORS & Open Token Endpoint
BeschreibungThis is a chained vulnerability combining three weaknesses into a single, remotely exploitable attack requiring only that the victim visits a malicious web page. The wildcard CORS policy (Access-Control-Allow-Origin: *) combined with the unauthenticated /token endpoint and lack of authentication on all routes enables zero-click remote credential theft. Any website visited by a user running copilot-api can steal the Copilot bearer token, exfiltrate usage data, and abuse the API through cross-origin JavaScript requests.
