# Escape of VM Context gives access to process level functionality ## Summary Happy DOM v19 and lower contains a security vulnerability that puts the owner system at the risk of RCE (Remote Code Execution) attacks. A Node.js VM Context is not an isolated environment, and if the user runs untrusted JavaScript code within the Happy DOM VM Context, it may escape the VM and get access to process level functionality. What the attacker can get control over depends on if the process is using ESM or CommonJS. With CommonJS the attacker can get hold of the `require()` function to import modules. Happy DOM has JavaScript evaluation enabled by default. This may not be obvious to the consumer of Happy DOM and can potentially put the user at risk if untrusted code is executed within the environment. ## Reproduce ### CommonJS (Possible to get hold of require) ```javascript const { Window } = require('happy-dom'); const window = new Window({ console }); window.document.write(` <script> ...

### Summary _Authlib’s JWE `zip=DEF` path performs unbounded DEFLATE decompression. A very small ciphertext can expand into tens or hundreds of megabytes on decrypt, allowing an attacker who can supply decryptable tokens to exhaust memory and CPU and cause denial of service._ ### Details - Affected component: Authlib JOSE, JWE `zip=DEF` (DEFLATE) support. - In `authlib/authlib/jose/rfc7518/jwe_zips.py`, `DeflateZipAlgorithm.decompress` calls `zlib.decompress(s, -zlib.MAX_WBITS)` without a maximum output limit. This permits unbounded expansion of compressed payloads. - In the JWE decode flow (`authlib/authlib/jose/rfc7516/jwe.py`), when the protected header contains `"zip": "DEF"`, the library routes the decrypted ciphertext into the `decompress` method and assigns the fully decompressed bytes to the plaintext field before returning it. No streaming limit or quota is applied. - Because DEFLATE achieves extremely high ratios on highly repetitive input, an attacker can craft a tiny `zip=...
