Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Armeria's armeria-xds module, versions before 1.40.0, resolves file names and environment variable names from xDS SDS secret resources without restricting them. A semi-trusted or compromised xDS control plane, or an attacker who can intercept SDS responses, can read arbitrary local files and environment variables on the client host. Upgrade to armeria-xds 1.40.0 or later. The source gives no workaround beyond securing the control plane channel with mTLS and auditing SDS configuration for file or environment-variable data sources.
