CVE-2026-55727 Overview
CVE-2026-55727 is an authentication bypass vulnerability in Genetec Security Center 5.14.0.0 prior to build 5.14.178.18. The flaw resides in the authentication mechanism for video stream requests. An unauthenticated remote attacker can access live video streams from affected systems without providing valid credentials.
The vulnerability is classified under [CWE-287] Improper Authentication. It is exploitable over the network with low attack complexity and requires no user interaction. Successful exploitation compromises the confidentiality of live surveillance footage handled by the platform.
Critical Impact
Unauthenticated remote attackers can retrieve live video streams from Genetec Security Center deployments, exposing surveillance feeds to unauthorized viewers.
Affected Products
- Genetec Security Center 5.14.0.0
- Genetec Security Center builds prior to 5.14.178.18
- Live video retrieval component of Security Center

Technical Details for CVE-2026-55727
Vulnerability Analysis
CVE-2026-55727 is an authentication bypass in the video stream request handler of Genetec Security Center. The affected component fails to enforce authentication checks on requests for live video retrieval. As a result, remote clients that reach the service over the network can request and receive live stream data without presenting valid session credentials.
The issue affects only version 5.14.0.0 of Security Center and is remediated in build 5.14.178.18. Because Security Center manages IP cameras and physical security infrastructure, exposure of live video streams has direct privacy and operational security consequences for facilities relying on the platform.
The EPSS score for this vulnerability is 0.291%, placing it in the 20.9 percentile as of 2026-07-09. No public exploit code or CISA KEV listing is currently associated with this CVE.
Root Cause
The root cause is improper authentication [CWE-287] within the video stream request path. The service accepts stream requests without validating that the caller has an authenticated session or authorization to view the requested resource. Authentication controls that apply to other Security Center interfaces are not consistently enforced on the live video retrieval endpoint.
Attack Vector
Exploitation occurs over the network. An attacker who can reach the video stream service of an affected Security Center deployment can issue requests for live streams directly. No credentials, prior access, or user interaction are required. The impact is scoped to confidentiality, with no direct impact on integrity or availability of the system.
Specific request formats and endpoint details are not published. See the Genetec Security Advisory for vendor guidance.
Detection Methods for CVE-2026-55727
Indicators of Compromise
- Unexpected outbound video stream sessions originating from Security Center servers to unknown external or internal IP addresses.
- Access logs showing video stream requests without corresponding authenticated user sessions.
- Anomalous spikes in bandwidth consumption on Security Center hosts tied to media streaming ports.
Detection Strategies
- Correlate video stream request logs with authentication events to identify stream deliveries that lack a preceding authenticated session.
- Baseline normal client IP ranges for Security Center video access and alert on requests from unexpected sources.
- Inspect network flows to and from the Security Center Media Server for connections that do not originate from approved workstations or mobile clients.
Monitoring Recommendations
- Enable verbose logging on the Security Center Media Server and forward logs to a centralized SIEM for correlation.
- Monitor firewall and network telemetry for direct access to Security Center services from untrusted network segments.
- Track version and build information across Security Center servers to identify unpatched hosts running builds earlier than 5.14.178.18.
How to Mitigate CVE-2026-55727
Immediate Actions Required
- Upgrade Genetec Security Center 5.14.0.0 to build 5.14.178.18 or later as provided by the vendor.
- Inventory all Security Center servers and confirm the running build version before and after patching.
- Restrict network access to Security Center Media Server ports so they are reachable only from trusted management and client networks.
Patch Information
Genetec has released a fixed build addressing the authentication bypass. Upgrade all affected servers to build 5.14.178.18 or later. Refer to the Genetec Security Advisory for detailed patch instructions and release notes.
Workarounds
- Segment Security Center servers onto a dedicated VLAN and enforce firewall rules that permit only approved client subnets to reach video stream services.
- Place Security Center behind a VPN so that video retrieval endpoints are not exposed to untrusted networks.
- Disable or restrict remote access features that are not required until the patched build has been deployed.
