TL;DR

Affected versions of this package are vulnerable to improper authorization: the AuthenticationProcessInterceptor sets the caller’s authentication in the shared SecurityContext but does not reliably clear it afterward, causing authentication information to leak across requests when threads are reused. As a result, a subsequent request may inherit a previous user’s identity and unintentionally pass @PreAuthorize checks.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.

Background info

spring-grpc-core is vulnerable to Authorization Bypass in versions 0.4.0 - 0.12.0.
