Q: Is there a fix for CVE-2026-70381?

Yes: fixed in Cynap Pure (Next Gen), Cynap Bridge: v2.00d; Cynap Pro, Cynap Core Pro, Cynap Receiver, Cynap Pure, Cynap Pure Mini, Cynap Pure Pro: v1.78a; Cynap Videobar: v1.72e. Until then: Restrict network access to the web management interfaces on TCP ports 80 and 443 to trusted hosts only. WolfVision recommends using dedicated, managed network segments (VLAN or firewall zone) to restrict device access to trusted hosts only. Discontinued models (Cynap, Cynap Core, Cynap Pure SDM) will not receive fixes and should be decommissioned or isolated to trusted networks.

CVE-2026-70381 · Severity: medium · CVSS 5.3 · Published 2026-10-26

WolfVision Cynap devices have a web-based management interface that controls presentation and collaboration equipment. An unauthenticated attacker with network access can bypass access controls to view non-public device content like screen-saver assets and web interface resources, though this does not expose credentials or administrative functions. The vulnerability allows unauthorized information disclosure about device configuration and internal resources.

Technical details

An access-control vulnerability in the web server configuration allows unauthenticated, network-based attackers to access internal resources that should only be available locally. The flaw stems from insufficient web request validation that fails to enforce boundary separation between internal and external network requests. While the exposed resources do not include credentials or enable administrative actions, they may reveal non-public device content and interface assets.
