TIMELINE Mar 10 Reserved by GitHub_M Mar 12 Published (CNA: GitHub_M) Aug 4 EXPLOIT PUBLISHED — CVE-2026-32141 (WebReflection flatted). Public exploit reference added.
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.
