NewCVE-2026-121821 (opens in a new tab)How to fix?
Upgrade com.linecorp.armeria:armeria to version 1.43.0 or higher.
Overview
com.linecorp.armeria:armeria is an asynchronous HTTP/2 RPC/REST client/server library built on top of Java 8, Netty, Thrift and gRPC (armeria)
Affected versions of this package are vulnerable to Incorrect Authorization via the getPolicy() function in CorsConfig. An attacker can make a victim’s browser send credentialed cross-origin requests and read responses from paths excluded by route() by hosting a page that requests those paths, when the server uses an any-origin CORS policy with allowCredentials(). Without credentials, the attacker can read only unauthenticated responses.
