CVE-2026-1749
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThere is an Access Control Vulnerability in some HikCentral Professional versions. This could allow an unauthenticated user to obtain the admin permission.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an access control vulnerability in HikCentral Professional that allows an unauthenticated user to gain administrative privileges. The vulnerability represents a critical privilege escalation flaw where the access control mechanism can be bypassed, permitting unauthorized users to obtain full admin access to the system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify HikCentral Professional installation and versionLocate the HikCentral Professional installation on the system. Check the management interface (System > About) or the installation directory for version information. The version is typically displayed in the system info or help/about section.Affected if Version matches unpatched releases and the authentication/authorization module is in use
-
Determine web service exposureCheck network configuration to see if HikCentral Professional web portal or API endpoints are accessible from network interfaces. Look for port 443 or 8443 bindings and firewall rules.Affected if The HikCentral Professional web interface is exposed to untrusted or public networks without VPN or IP restrictions
-
Audit administrator accountsReview user management in HikCentral Professional (typically under System > User Management or Security > Users) for any admin-level accounts that were not created by legitimate administrators.Affected if Unexpected administrator accounts exist or account creation timestamps correlate with potential attack periods
-
Examine authentication logs for privilege escalationSearch HikCentral Professional audit and security logs for events indicating privilege level changes, particularly from unauthenticated or standard user context to administrator role.Affected if Logs show unauthorized privilege escalation attempts or successful escalations from unauthenticated sessions
-
Verify authorization configurationCheck the security/authorization settings in HikCentral Professional to confirm whether role-based access control (RBAC) is properly enforced for all API endpoints and administrative functions.Affected if Authorization checks are missing or disabled for critical administrative functions
Environment is affected if HikCentral Professional is running with unpatched versions, has its web interface exposed to untrusted networks, and shows evidence of unauthorized admin account creation or privilege escalation activity in logs or configuration.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied patches or updates to HikCentral Professional to remediate the access control vulnerability. If patches are unavailable, implement network segmentation and restrict access to the management interface to trusted IP addresses.
