CVE-2026-56841
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 · uneditedA malicious actor with access to the network and low privileges could exploit an authenticated SQL Injection vulnerability found in UniFi Protect Application to escalate privileges on the host device.
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 confidenceAn authenticated SQL injection vulnerability exists in UniFi Protect Application that allows a low-privileged attacker with network access to escalate privileges on the host device. The vulnerability stems from improper input sanitization in database queries, enabling malicious SQL commands to be executed through authenticated user inputs.

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 UniFi Protect installationLocate the UniFi Protect Application installation and determine its version using the vendor's standard method for checking software version (typically via the controller UI, command line, or system information)Affected if UniFi Protect Application is installed and the version is below 7.1.83
-
Verify installed version numberCompare your installed UniFi Protect Application version against the affected range: any version less than 7.1.83 is vulnerableAffected if The installed version is less than 7.1.83
-
Assess network exposureDetermine if the UniFi Protect management interface is accessible from untrusted network segments, as the vulnerability requires network access for an authenticated attackerAffected if The UniFi Protect interface is exposed to untrusted or public networks without proper access controls
-
Review user account configurationCheck for the presence of low-privileged user accounts within UniFi Protect, as the vulnerability can be exploited by a low-privileged authenticated userAffected if Low-privileged accounts exist and can access the UniFi Protect interface from an exposed network
Your environment is affected if UniFi Protect Application is running a version below 7.1.83 and is accessible to authenticated users on untrusted networks.
Generated from the published advisory. Verify against your own 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.
dbcve · scoped7.1.83
Upgrade UniFi Protect Application to the vendor-provided patched version. If no patch is available, implement input validation and parameterized queries for all database interactions, and restrict network access to trusted users.
UniFi Protect version 7.1.83 or later (recommended: latest stable release)
- 1. Log in to the UniFi OS Console hosting the UniFi Protect application
- 2. Navigate to the UniFi Protect settings or system management section
- 3. Check the current UniFi Protect version to confirm it is below 7.1.83
- 4. Initiate the update through the UniFi OS interface - look for an 'Update' or 'Upgrade' option for UniFi Protect
- 5. Wait for the update to download and install completely
- 6. Verify the installation was successful by checking the new version number is 7.1.83 or higher
- 7. Confirm the application is functioning normally after the upgrade
