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
Deserialization of Untrusted Data vulnerability in masikonis Geolocator geolocator allows Object Injection.This issue affects Geolocator: from n/a through <= 1.1.

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

The Geolocator package by masikonis contains an insecure deserialization vulnerability (Object Injection) that allows remote attackers to inject malicious objects by supplying untrusted serialized data. This is exploitable network-wide (CVSS 9.8) and can lead to remote code execution.

MitigationUpgrade to a patched version of Geolocator (version > 1.1) once available. Avoid deserializing data from untrusted sources and implement input validation on all data ingestion points.

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. Locate Geolocator package in your project
    Search your codebase for references to 'Geolocator' in project files (.csproj, packages.config, .vbproj), NuGet package references, or import statements. Also check any dependency manifest files.
    Affected if The Geolocator package by masikonis is present in your project dependencies
  2. Identify the installed version of Geolocator
    Check the version number in your NuGet package manager, package references file, or lock file (packages.lock.json). Compare this version against the affected range (version 1.1 and below).
    Affected if The Geolocator version is 1.1 or lower
  3. Find deserialization usage of Geolocator data
    Search your codebase for deserialization methods (BinaryFormatter, ObjectInputStream, JSON deserialize, XML deserialize, pickle, yaml.load, or similar) used on data processed by Geolocator or received from network sources.
    Affected if Your application deserializes data from Geolocator or untrusted network sources without validation
  4. Verify network exposure of Geolocator functionality
    Review if Geolocator-processed data or serialized Geolocator objects are received over network connections, APIs, message queues, or stored in databases accessible by other systems.
    Affected if Geolocator data containing serialized objects is received from untrusted network sources

You are affected if Geolocator version 1.1 or lower is installed AND your application deserializes data from untrusted or network sources using that package.
