+# Solution contains packages with vulnerabilities
+
+Sometimes, especially when using an older version of Stride, you might notice warnings in Visual Studio that look like this:
+
+![This solution contains packages with vulnerabilities.](media/visual-studio-vulnerable-packages-warning.webp)
+
+![Warnings in the Error List, saying that a package has a known high severity vulnerability.](media/visual-studio-error-list-vulnerable-packages-warnings.webp)
+
+...or when building your project:
+
+![The terminal displaying multiple warnings, saying that a package has a known high severity vulnerability.](media/terminal-vulnerable-packages-warnings.webp)
+
+## What does it mean?
+
+This means that one of the **external packages** your project is using has been marked as vulnerable and **could be exploited by bad actors in your released game**.
+
+## Why does it happen?
+
+Stride depends on **other libraries** in order to work and sometimes, those libraries are **marked as vulnerable on [nuget.org](https://nuget.org)**.
+
+## How to fix it?
+
+1. Update your project to the latest version of Stride. See [Update Stride](../install-and-update/update-stride.md).
+2. Check in the engine's [source code](https://github.com/stride3d/stride) if the warning is limited to Game Studio, in which case it can be safely ignored.
+3. Ignore the warning while you work on your game and wait for the next release of the engine.
+
+This warning **does not impact your ability to develop and build**. You are still able to use the editor, test your game and even release it (see the note below).
+
+> [!NOTE]
+> If you want to release a game with vulnerable packages, make sure to **check how the vulnerability would impact your users** and decide if the warnings can be ignored. If you can't wait, you will have to **build the engine from source**.
