CVE-2026-82433
| Severity | 6.5 Medium CVSS 3.1 |

| Weakness | Missing authorization (CWE-862) |
| Published | 14 Sep 2026 |
Published 2 months ago. NVD often adds the list of affected products days or weeks after a CVE is published, and the other sources we check lag too. The scope and status here may change.
Description
Description
getNimbusConf returned the complete daemon configuration without redaction after only a user-level
authorization check. Where the cluster is configured with them, that response includes
storm.zookeeper.auth.payload and the keystore and truststore passwords for the Thrift, Netty and
ZooKeeper TLS configuration. The project masks passwords elsewhere before display, so the omission here is
inconsistent rather than intended.
The UI endpoint /api/v1/cluster/configuration compounded this. It carried no @AuthNimbusOp annotation,
and the authorization filter treated a missing annotation as "no gate required" and returned immediately, so
the endpoint applied no per-user check at all and proxied the request under the UI daemon's own principal.
Any user able to pass ui.filter therefore received the full configuration, including principals that
Nimbus itself would have refused.
Mitigation
Upgrade to 3.1.0, where credential-bearing values are masked before the configuration is served and where
every UI API endpoint must declare its authorization explicitly.
Users who cannot upgrade immediately should place the UI behind an authenticating reverse proxy that
restricts /api/v1/cluster/configuration, and should rotate the ZooKeeper authentication payload and any
TLS keystore or truststore passwords that were reachable through it.

| Decided by | Nothing to build a rule from yet: no published exploit, no CISA record of exploitation and no source-level change to read |
|---|---|
| Finding | This CVE affects a known product, but nothing published names a fix and nothing published shows an exploit. That is a statement about the evidence, not about the defect — it does not mean the vulnerability is unimportant or unreachable, only that neither of the two things VRT can act on exists. |
