### Impact Prototype pollution vulnerability in merge(). If application code calls `rollbar.configure()` with untrusted input, prototype pollution is possible. ### Patches Fixed in 2.26.5 and 3.0.0-beta5. ### Workarounds Ensure that values passed to `rollbar.configure()` do not contain untrusted input. ### References Fixed in https://github.com/rollbar/rollbar.js/pull/1394 (2.26.x) and https://github.com/rollbar/rollbar.js/pull/1390 (3.x)

### Impact **Development mode only**. Kottster contains a pre-authentication remote code execution (RCE) vulnerability when running in development mode. The vulnerability combines two issues: 1. The `initApp` action can be called repeatedly without checking if the app is already initialized, allowing attackers to create a new root admin account and obtain a JWT token 2. The `installPackagesForDataSource` action uses unescaped command arguments, enabling command injection An attacker with access to a locally running development instance can chain these vulnerabilities to: - Reinitialize the application and receive a JWT token for a new root account - Use this token to authenticate - Execute arbitrary system commands through `installPackagesForDataSource` **Production deployments were never affected.** ### Patches Fixed in [v3.3.2](https://github.com/kottster/kottster/releases/tag/v3.3.2). Specifically, `@kottster/server` [v3.3.2](https://www.npmjs.com/package/@kottster/server/v/3...
