IdentifiersCVE-2026-41723CWE-79

CVE-2026-41723 is a stored cross-site scripting vulnerability affecting VMware Cloud Foundation Operations. According to the provided advisory content, the product contains multiple stored XSS flaws that can be triggered by a malicious actor who has privileges to create policies, views, or text widgets. By injecting malicious script content into these stored objects, the attacker can cause the script to execute later in another user's browser when the affected content is rendered in the VMware Cloud Foundation Operations interface. The available description indicates that successful exploitation can be used to perform administrative actions within VMware Cloud Foundation Operations.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an attacker with low-level authenticated privileges sufficient to create policies, views, or text widgets to execute attacker-controlled script in the context of a victim user's browser session. If an administrative user views the malicious content, the attacker may be able to perform administrative actions in VMware Cloud Foundation Operations. Based on the provided CVSS v3.1 vector (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H), the vulnerability can have high impact on confidentiality, integrity, and availability.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure by limiting which users can create or modify policies, views, and text widgets; reviewing and removing untrusted or user-supplied content from those objects; monitoring administrative dashboards for suspicious embedded script content; and restricting access to the management interface to trusted administrators only. These are interim risk-reduction measures only; vendor patches are the primary mitigation.

Remediation

Patch, then assume compromise.

Broadcom has provided security updates to remediate this issue. The provided content states that administrators should apply the latest patches immediately and identifies VMware Aria Operations version 8.18.6 as a fixed version in the related product line. Organizations should review the Broadcom security advisory for CVE-2026-41723 and upgrade affected VMware Cloud Foundation Operations and related deployments to the vendor-fixed versions.
