Vulnerability from github – Published: 2026-10-21 12:31 – Updated: 2026-10-21 12:31

Details

When ServerOptions.auth is enabled and builtin HTTP services are exposed on the public listener, a builtin request received as the first message on a socket may cause the connection to be treated as authenticated for later requests on that socket. Users are recommended to upgrade to version 1.18.0, which fixes this issue, or apply this PR separately: https://github.com/apache/brpc/pull/3308

CVE-2026-48830 (GCVE-0-2026-48830)

Vulnerability from cvelistv5 – Published: 2026-10-21 11:30 – Updated: 2026-10-21 11:30

Title

Apache bRPC: HTTP builtin request can mark a connection authenticated and bypass auth for later requests

Summary

Improper authentication in Apache bRPC through 1.17.0 allows a remote unauthenticated attacker to bypass authentication for protected non-builtin HTTP endpoints by first sending a builtin HTTP request on the same HTTP/1.1 keep-alive connection. When ServerOptions.auth is enabled and builtin HTTP services are exposed on the public listener, a builtin request received as the first message on a socket may cause the connection to be treated as authenticated for later requests on that socket. Users are recommended to upgrade to version 1.18.0, which fixes this issue, or apply this PR separately: https://github.com/apache/brpc/pull/3308
