CVE-2026-82428Not yet in NVD's feed. The description, CVSS and CWE below come from the CVE Numbering Authority's own record, not from NVD analyst review. NVD's own page for this identifier may not exist yet.
Published yesterday. NVD backfills CPE data for days or weeks after publication, and OSV and the exploit indexes lag too. Scope and status here may change.
Description
Dependency artifacts uploaded with storm jar --artifacts were stored under a blob key derived only from
the Maven coordinate, for example dep---.jar. The key was therefore identical
for every user of the cluster and predictable in advance. When the blob already existed, the uploader
caught KeyAlreadyExistsException and silently reused it, with no check that the existing blob's content
or owner matched the artifact the submitter had resolved.
A user who uploaded a blob under such a key first therefore controlled the bytes that every later submitter
of the same coordinate would receive on the worker classpath, resulting in code execution inside another
tenant's topology.
This affects deployments where more than one principal may create blobs and where the --artifacts
dependency feature is used.
Mitigation
Upgrade to 3.1.0, where each uploaded artifact receives a key carrying a freshly generated UUID and a
pre-existing blob is no longer silently reused.
Note that the corrected key generation is on the SUBMITTING CLIENT, so upgrading the cluster alone does not
close this; every client that runs storm jar --artifacts must also be upgraded. Operators should audit
existing dep- blobs for unexpected owners before upgrading. Users who cannot upgrade immediately should
avoid the --artifacts mechanism in multi-tenant clusters and distribute dependencies inside the topology
jar instead.
