Remote Control for Zoom Contact Center CVE-2026-53406

Exploitation requires local access to a Windows endpoint that has Remote Control for Zoom Contact Center installed at a version below 7.0.0, and the attacker must already hold valid low-privileged authenticated access on that host (CVSS PR:L). No user interaction is required (UI:N), and attack complexity is low (AC:L), but exploitation is bounded to hosts where the vulnerable component is actually deployed - typically contact-center agent workstations rather than general-purpose endpoints - and to attackers who have already obtained an initial foothold, which excludes purely remote unauthenticated abuse.

The CVSS 3.1 vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H indicates a local, low-complexity attack requiring only low privileges, with no user interaction and full CIA impact - consistent with a classic Windows local privilege escalation. EPSS data was not provided in the input, and CISA KEV does not list this CVE, so no evidence of active exploitation exists; combined with no public POC, real-world risk today is moderate rather than urgent. The principal limiting factor is the requirement for a foothold on a Windows endpoint that already runs the Zoom Contact Center remote-control component, which narrows the population of vulnerable hosts to contact-center agent workstations. Defenders should treat this as a meaningful post-exploitation hardening item - especially relevant to threat models involving malicious insiders or chained attacks - rather than an emergency patch event.

A malicious insider or an attacker who has already obtained low-privileged code execution on a contact-center agent's Windows workstation - for example via a phishing payload - runs a local tool that crafts unauthenticated data accepted by the privileged Remote Control component. The component acts on this data without verifying its authenticity, yielding code execution or token theft in the privileged context and escalating the attacker from a standard user to SYSTEM or an equivalent high-integrity context. No public POC is identified at time of analysis, so exploitation would currently require independent development.
