Doc Text:
A flaw was found in the Apache Storm storm-server component. The Distributed Remote Procedure Call (DRPC) HTTP endpoint fails to enforce the configured impersonation authorizer on incoming client requests. An authenticated attacker can exploit this flaw to act as another user and execute restricted functions, leading to unauthorized access and privilege escalation.

Description OSIDB Bzimport 2026-11-11 12:41:23 UTC
The DRPC HTTP endpoint lets an authenticated client act as another user without applying the configured impersonation authorizer. An authenticated user can execute DRPC functions that are restricted to another user. Users are recommended to upgrade to version 3.2.0, which fixes the issue.
