Broadcom has issued VMware advisory VMSA-2026-0008 for a critical vulnerability in VMware SDDC Manager, tracked as CVE-2026-111497. The flaw stems from a remote code‑execution issue in the Node.js Brotli decoder used within SDDC Manager, allowing an attacker with network access to execute arbitrary code by sending a crafted Brotli‑compressed stream.

VMware notes this vulnerability has a maximum CVSS v3 score of 9.8 on SDDC Manager 9.1.1, with lower scores of 7.5 for the 9.0.x and 9.1.0 branches and for 5.2.x in its broader product lines. CISA confirmed active exploitation of the Brotli library in general on 27 October, while Broadcom states the critical score applies specifically to SDDC Manager 9.1.1.x and not to older releases.

Do Son, writing for SecurityOnline[.]info, reports that Broadcom’s advisory points to a remote‑code‑execution vector via a memory corruption in the Brotli decoder, and that a malicious actor could exploit this by sending a crafted Brotli stream to SDDC Manager.

Affected versions cited include SDDC Manager 9.1.1 (CVSS 9.8), SDDC Manager 9.0.x and 9.1.0 (CVSS 7.5), and SDDC Manager 5.2.x (CVSS 7.5). Patches are listed as pending across the response matrix, with Broadcom directing KB460732 for 9.1.1 and KB460734 for older branches as interim guidance. In the interim, the article advises restricting network access to SDDC Manager to trusted admin hosts.

The report attributes these findings to Broadcom’s advisory and CISA KEV listings, with VMware’s statements framing the impact as a potential takeover of control within VMware Cloud Foundation and related environments. The piece identifies CISA’s KEV inclusion on 27 October and reiterates that Broadcom has not yet reported attacks against SDDC Manager itself.
