Vulnerability Details

Stack overflow vulnerability in eslint before 9.26.0 when serializing objects with circular references in eslint/lib/shared/serialization.js. The exploit is triggered via the RuleTester.run() method, which validates test cases and checks for duplicates. During validation, the internal function checkDuplicateTestCase() is called, which in turn uses the isSerializable() function for serialization checks. When a circular reference object is passed in, isSerializable() enters infinite recursion, ultimately causing a stack overflow.

Path to vulnerable library: /package.json

Dependency Hierarchy:

• eslint-7.32.0.tgz (Root Library)

Found in HEAD commit: e1db6833fb15baf6aa472bac4d5a4279dd618797

Found in base branch: main

Vulnerability Details

js-yaml is a JavaScript YAML parser and dumper. In js-yaml 4.1.0 and below, it's possible for an attacker to modify the prototype of the result of a parsed yaml document via prototype pollution ("proto"). All users who parse untrusted yaml documents may be impacted. The problem is patched in js-yaml 4.1.1. Users can protect against this kind of attack on the server by using "node --disable-proto=delete" or "deno" (in Deno, pollution protection is on by default).
