Severity

medium6.5

CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

A flaw in StreamsHub Console for Apache Kafka versions 0.2.1 to 0.12.9 and 0.13.0 to 0.14.1 allows a Console CR author to exfiltrate the console-api ServiceAccount token. The vulnerability occurs due to unfiltered Kafka client properties. An attacker with access to create or update Console custom resources can exploit this weakness.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

Restrict create, update, and patch permissions for Console custom resources to trusted administrators only. Where supported, apply a NetworkPolicy to restrict Console API egress to approved Kafka broker endpoints. These controls reduce exposure to the reported ServiceAccount-credential disclosure path but do not replace the permanent fix, which is to filter security-sensitive Kafka client properties. Upgrade to a release containing the permanent fix when available.

Original source description

Read the full publisher description

A flaw was found in the StreamsHub Console for Apache Kafka. Tenant-supplied Kafka client properties from the Console custom resource are copied into the console-api AdminClient configuration without filtering security-sensitive keys, allowing a Console CR author to set config.providers and bootstrap.servers to exfiltrate the console-api ServiceAccount token to an attacker-controlled broker.
