flatted: Unbounded recursion DoS in parse() revive phase
CVE-2026-32141 is fixed in node-flatted on 1 platform by DEBIAN-CVE-2026-32141 (version 3.4.1~ds-1), released March 12, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
