SCA: security update for org.apache.storm:storm-client (GHSA-jf89-3q6q-vcgr)

high Tenable Self-Hosted Container Security Plugin ID 440429

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Deserialization of Untrusted Data vulnerability in Apache Storm. Versions Affected: before 2.8.6.
 Description: When processing topology credentials submitted via the Nimbus Thrift API, Storm deserializes
 the base64-encoded TGT blob using ObjectInputStream.readObject() without any class filtering or
 validation. An authenticated user with topology submission rights could supply a crafted serialized object
 in the "TGT" credential field, leading to remote code execution in both the Nimbus and Worker JVMs.
 Mitigation: 2.x users should upgrade to 2.8.6. Users who cannot upgrade immediately should monkey-patch an
 ObjectInputFilter allow-list to ClientAuthUtils.deserializeKerberosTicket() restricting deserialized
 classes to javax.security.auth.kerberos.KerberosTicket and its known dependencies. A guide on how to do
 this is available in the release notes of 2.8.6. Credit: This issue was discovered by K. (CVE-2026-35337)

Solution

Update the org.apache.storm:storm-client library and its related packages to version 2.8.6 or later.
