Virtual Storage Integrator for VMware vSphere…: Exposure of Sensitive Information to an Unauthorized Actor
CVE-2026-54489 is a critical-severity exposure of sensitive information to an unauthorized actor vulnerability in Virtual Storage Integrator for VMware vSphere Client from Dell, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 10.11.1.0 or later as the first without the flaw, so updating Virtual Storage Integrator for VMware vSphere Client to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.62% chance of exploitation within 30 days, higher than 50% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Virtual Storage Integrator for VMware vSphere Client to 10.11.1.0 or later or a later version.
- Update Virtual Storage Integrator to 10.11.1.0 or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Dell Virtual Storage Integrator for VMware vSphere Client, versions prior to 10.11.1.0, contain(s) a Sensitive Information Disclosure vulnerability. An unauthenticated remote attacker could potentially exploit this vulnerability, leading to information disclosure and session hijacking. This vulnerability is considered critical as it allows an unauthenticated attacker to obtain active session credentials and fully impersonate authenticated users, including administrators. Dell recommends customers to upgrade at the earliest opportunity.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How developers prevent this class of flaw
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
