GHSA-5G75-477J-2C2F LaunchServer FileServerHandler has an unauthenticated path traversal issue

Summary An unauthenticated path traversal in the LaunchServer HTTP file server FileServerHandler lets any remote actor read any file readable by the LaunchServer process e.g. ../../../../etc/passwd. This is a generic arbitrary-file-read primitive, so the fix must address the traversal itself, not...

GHSA-7FQC-P256-7PWJ Steeltoe's static JWKS cache shared across schemes and never invalidated

Summary The JWT signing key cache in TokenKeyResolver uses kid as the sole cache key without namespacing by authority. In applications with multiple JwtBearer schemes pointing to different identity providers, a key fetched for one scheme can satisfy token validation for another. Additionally,...
