**Name of the Vulnerable Software and Affected Versions** vm2 versions prior to 3.11.0 **Description** A flaw in the Node.js sandbox library allows sandboxed code to obtain the host `Object`. This occurs due to incorrect code generation management and incomplete protections. An attacker can use the host `Object` to bypass isolation and execute arbitrary code on the host system. One method of exploitation involves using `HostObject.getOwnPropertySymbols` to obtain `Symbol(nodejs.util.inspect.custom)`. **Recommendations** Update vm2 to version 3.11.0.

**Name of the Vulnerable Software and Affected Versions** vm2 versions prior to 3.11.0 **Description** A sandbox escape allows unauthenticated attackers to execute arbitrary system commands (RCE) on the host. The issue occurs because `BaseHandler.getPrototypeOf` can be reached via `util.inspect`, enabling the retrieval of arbitrary prototypes. By manipulating object prototypes through internal bridge functions, an attacker can gain access to the host's process object. **Recommendations** Update to version 3.11.0.

**Name of the Vulnerable Software and Affected Versions** n8n versions prior to 2.14.1 n8n versions prior to 2.13.3 n8n versions prior to 1.123.26 **Description** n8n is a workflow automation platform. A user authenticated with permissions to create or modify workflows could leverage the "Combine by SQL" mode within the Merge node to read local files on the n8n host and potentially achieve remote code execution. The AlaSQL sandbox lacked sufficient restrictions on certain SQL statements, enabling an attacker to access sensitive files on the server or compromise the instance. The vulnerable component is the Merge node and its use of AlaSQL. **Recommendations** Upgrade to n8n version 2.14.1 or later. Upgrade to n8n version 2.13.3 or later. Upgrade to n8n version 1.123.26 or later. If upgrading is not immediately possible, limit workflow creation and editing permissions to fully trusted users only. If upgrading is not immediately possible, disable the Merge node by adding `n8n-nodes-base.merge` to the `NODES EXCLUDE` environment variable.

**Name of the Vulnerable Software and Affected Versions** SandboxJS versions prior to 0.8.34 **Description** SandboxJS is a JavaScript sandboxing library susceptible to a sandbox escape. The issue arises from the ability to obtain arrays containing the `Function` constructor. Combined with `Object.fromEntries`, this allows constructing objects with properties that can execute arbitrary code, leading to a complete escape of the sandbox. The provided Proof of Concept (PoC) demonstrates the exploitation of this issue using `process.getBuiltinModule("child process").execSync("ls", {stdio: "inherit"})` to execute system commands. The vulnerability can result in Remote Code Execution (RCE). The API endpoint is not explicitly mentioned. The vulnerable variable is `Function`. **Recommendations** Versions prior to 0.8.34 should be updated to version 0.8.34 or later.

**Name of the Vulnerable Software and Affected Versions** n8n versions prior to 2.10.1 n8n versions prior to 2.9.3 n8n versions prior to 1.123.22 **Description** n8n is an open source workflow automation platform. An authenticated user with permission to create or modify workflows could exploit a weakness in the JavaScript Task Runner sandbox to execute code outside of its intended boundary. When using the default internal Task Runners, this could lead to a complete compromise of the n8n host system. If external Task Runners are in use, an attacker might gain access to or disrupt other tasks running on the Task Runner. The Task Runners must be enabled using the `N8N RUNNERS ENABLED=true` setting. Reports indicate over 100,000 servers are potentially affected, with a significant concentration in the United States and a notable presence in Russia. **Recommendations** Upgrade to n8n version 2.10.1 or later. Upgrade to n8n version 2.9.3 or later. Upgrade to n8n version 1.123.22 or later.

**Name of the Vulnerable Software and Affected Versions** Enclave versions prior to 2.11.1 **Description** Enclave is a secure JavaScript sandbox used for safe AI agent code execution. A critical security flaw exists in versions prior to 2.11.1, allowing an attacker to escape the sandbox boundaries and achieve remote code execution (RCE) on the underlying host system. This is possible due to the ability to obtain the native `Object` constructor, allowing access to restricted properties and host functions. Two proof-of-concept exploits are described, one leveraging ` host memory track ` when a memory limit is set, and another utilizing Node's `nodejs.util.inspect.custom` symbol when a memory limit is not set. Successful exploitation results in arbitrary command execution on the host, representing a full system compromise. **Recommendations** Upgrade to version 2.11.1 or later immediately.

**Name of the Vulnerable Software and Affected Versions** SandboxJS versions prior to 0.8.29 **Description** SandboxJS is a JavaScript sandboxing library affected by an issue where the return values of functions are not properly wrapped. This allows attackers to use `Object.values` or `Object.entries` to obtain an array containing the host's `Function` constructor. By utilizing `Array.prototype.at`, the host's `Function` constructor can be accessed, enabling the execution of arbitrary code outside of the sandbox. The provided proof-of-concept code demonstrates how to leverage this to execute commands like 'ls -lah' using the `child process` module. The vulnerability allows for sandbox escape, potentially leading to remote code execution (RCE). **Recommendations** Versions prior to 0.8.29 should be updated to version 0.8.29 or later.

**Name of the Vulnerable Software and Affected Versions** SandboxJS versions prior to 0.8.29 **Description** SandboxJS is a JavaScript sandboxing library. Prior to version 0.8.29, a flaw exists where the prototype of the `Map` object, present in `SAFE PROTOYPES`, can be accessed via `Map.prototype`. By overwriting the `Map.prototype.has` function, the sandbox can be escaped, potentially leading to remote code execution. The issue stems from a bug in the `let` implementation, where using `let` instead of `const` to declare a variable referencing `Map.prototype` results in `undefined`. This allows manipulation of the `Map.prototype.has` function. A proof-of-concept (PoC) demonstrates the ability to execute arbitrary commands, such as listing directory contents, by redefining `Map.prototype.has` to call `isFinite.constructor` with a malicious string. **Recommendations** Versions prior to 0.8.29 should be updated to version 0.8.29 to address this issue.

**Name of the Vulnerable Software and Affected Versions** n8n versions prior to 2.4.8 **Description** n8n is a workflow automation platform. A flaw in the Python Code node allows authenticated users to bypass the Python sandbox and run code outside the intended security limits. The vulnerability allows for arbitrary code execution on the host system. **Recommendations** Update to version 2.4.8 or later.

**Name of the Vulnerable Software and Affected Versions** SandboxJS versions prior to 0.8.27 **Description** SandboxJS is a JavaScript sandboxing library with an issue where the ` lookupGetter ` function is not properly restricted. This can allow obtaining prototypes, potentially leading to sandbox escape and remote code execution. The issue affects versions prior to 0.8.27. **Recommendations** Update to SandboxJS version 0.8.27 or later.

**Name of the Vulnerable Software and Affected Versions** Mattermost Mobile versions <= 2.22.0 **Description** The issue allows an attacker to crash the mobile application via crafted malicious input. This is due to the failure to properly validate the style of proto supplied to an action's style in post.props.attachments. **Recommendations** For Mattermost Mobile versions <= 2.22.0, update to a version greater than 2.22.0 to resolve the issue. As a temporary workaround, consider restricting the use of attachments in posts to minimize the risk of exploitation.
