AmoyLab Unla through 0.10.0 OAuth2 Authentication Bypass via /authorize

Type: advisorySource: Official CVE List1 source record

AmoyLab Unla through 0.10.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to obtain valid access tokens because the OAuth2 server never authenticates a resource owner. Attackers can register a client, request a code from /authorize, and exchange it at /token to access OAuth2-protected MCP prefixes, proxied upstream APIs and injected credentials.
