Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

CVE published 28 Sep 2026
Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 13 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Restrict create, update, and patch permissions for Console custom resources to trusted administrators only. Where supported, apply NetworkPolicy to restrict Console API egress to approved Kafka broker endpoints. These mitigations reduce exposure to token exfiltration but do not replace the permanent fix. Upgrade to StreamsHub Console versions 0.12.9 or 0.14.1 or later, which include filtering of security-sensitive Kafka client properties.

Description

CVE-2026-96740 is a vulnerability in the StreamsHub Console for Apache Kafka where tenant-supplied Kafka client properties are copied into the console-api AdminClient configuration without filtering security-sensitive keys. This allows an authenticated Console custom resource author to configure properties that can exfiltrate the console-api ServiceAccount token to an attacker-controlled Kafka broker. Exploitation requires authenticated cluster access with privileges to create or modify Console custom resources. The vulnerability is rated medium severity with a CVSS score of 6.5. Fixed versions are 0.12.9 and 0.14.1.

Impact

An attacker with authenticated cluster access and privileges to create or alter Console custom resources can exfiltrate the console-api ServiceAccount token by injecting malicious Kafka client properties. This token disclosure can lead to privilege escalation within the cluster. The vulnerability does not impact integrity or availability but has a high confidentiality impact. Environments restricting Console resource creation to trusted administrators reduce the risk.
