flatted: Unbounded recursion DoS in parse() revive phase

Exploitation and risk

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

cve-program · CVE-2026-32141

Published

flatted is a circular JSON parser. Prior to 3.4.0, flatted's 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. This vulnerability is fixed in 3.4.0.

## Summary flatted's `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 `$` indices, the recursion depth is unbounded, causing a stack overflow that crashes the Node.js process. ## Impact Denial of Service (DoS). Any application that passes untrusted input to `flatted.parse()` can be crashed by an unauthenticated attacker with a single request. flatted has ~87M weekly npm downloads and is used as the circular-JSON serialization layer in many caching and logging libraries. ## Proof of Concept ```javascript const flatted = require('flatted'); // Build deeply nested circular reference chain const depth = 20000; const arr = new Array(depth + 1); arr[0] = '{"a":"1"}'; for (let i = 1; i <= depth; i++) { arr[i] = `{"a":"${i + 1}"}`; } arr[depth] = '{"a":"leaf"}'; const payload = JSON.stringify(arr); flatted.parse(payload); // RangeError: Maximum call stack size exceeded ``` ## Fix The maintainer has already merged an iterative (non-recursive) implementation in PR #88, converting the recursive `revive()` to a stack-based loop. ## Affected Versions All versions prior to the PR #88 fix.
