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 · unedited
Snipe-IT before 8.1.18 allows unsafe deserialization.

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 confidence

Snipe-IT versions prior to 8.1.18 contain an unsafe deserialization vulnerability. This class of flaw allows attackers to manipulate serialized data during the deserialization process, potentially leading to remote code execution when the application processes maliciously crafted input.

MitigationUpgrade Snipe-IT to version 8.1.18 or later to remediate the unsafe deserialization vulnerability. If immediate patching is not possible, consider network-level restrictions and input validation as temporary compensating controls.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Snipe-IT installation exists
    Identify whether Snipe-IT web application is deployed in your environment by checking for the Snipe-IT application directory, web server virtual host configuration, or by accessing the application URL
    Affected if Snipe-IT is not present in your environment
  2. Locate the installed version file
    Check common locations for version information: (1) Look for a version file in the application root (often named 'version' or 'VERSION'), (2) Check composer.json for the 'app.version' field, (3) Access the admin dashboard and look for version information typically displayed in the footer or under 'System Information' in settings
    Affected if You cannot locate a version indicator in expected locations
  3. Compare installed version to affected range
    Examine the discovered version number and compare it numerically or textually against 8.1.18. Versions are typically formatted as major.minor.patch (e.g., 8.1.17, 8.1.0, 8.0.0)
    Affected if The installed version is 8.1.17 or lower, or any version beginning with 8.0.x or lower numeric sequences
  4. Check for version display in application UI
    If the application is accessible, log in as an administrator and navigate to the Settings or About page. The version is typically displayed in the footer of the application interface or under the 'System Information' section
    Affected if The UI displays a version lower than 8.1.18
  5. Verify deserialization handling in codebase
    If you have source code access, search for PHP unserialize() function calls that process user-controlled input without prior validation. Look in controller files and service classes that handle serialized data submissions
    Affected if Code contains unserialize() calls processing untrusted input and the version is below 8.1.18

You are affected if Snipe-IT is installed and the running version is any version lower than 8.1.18, as this unsafe deserialization vulnerability exists in versions prior to that release.

Upgrade available Upgrade to 8.1.18 or later
Fixed in 8.1.18
Interim mitigation

Upgrade Snipe-IT to version 8.1.18 or later to remediate the unsafe deserialization vulnerability. If immediate patching is not possible, consider network-level restrictions and input validation as temporary compensating controls.

Recommended fix Moderate confidence

8.1.18

  1. Backup your current Snipe-IT installation and database before upgrading
  2. Download Snipe-IT version 8.1.18 from the official GitHub repository or release page
  3. Extract the new version files to your server, preserving your configuration and .env file
  4. Run database migrations if required: php artisan migrate
  5. Clear application cache: php artisan cache:clear
  6. Verify the upgrade was successful by checking the version number in the admin interface
