What is CVE-2026-11752?

A security flaw has been discovered in armeria-xds versions 1.38.0 through 1.39.0. The DataSourceStream component within the xDS module is susceptible to unauthorized file and environment variable access. This occurs when it resolves control-plane-supplied filenames and environment variables without proper restrictions. As a result, a compromised or trusted xDS control plane can read arbitrary local files and sensitive environment variables from the xDS client host, posing a significant risk of data exposure.

Affected Version(s)

Armeria 1.38.0 < 1.40.0
