{"id":"CVE-2026-32141","summary":"flatted: Unbounded recursion DoS in parse() revive phase","details":"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.","aliases":["GHSA-25h7-pfq9-p65f"],"modified":"2026-03-24T03:02:40.603301Z","published":"2026-03-12T18:08:09.634Z","related":["CGA-j4x5-cp3m-97fw"],"database_specific":{"cwe_ids":["CWE-674"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32141.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32141.json"},{"type":"ADVISORY","url":"https://github.com/WebReflection/flatted/security/advisories/GHSA-25h7-pfq9-p65f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32141"},{"type":"FIX","url":"https://github.com/WebReflection/flatted/commit/7eb65d857e1a40de11c47461cdbc8541449f0606"},{"type":"FIX","url":"https://github.com/WebReflection/flatted/pull/88"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/webreflection/flatted","events":[{"introduced":"0"},{"fixed":"d3418c718160eae69dbc0405dce75f7849019e1e"}]}],"versions":["v0.1.0","v0.2.0","v0.2.1","v0.2.2","v0.2.3","v1.0.0","v1.0.1","v1.0.2","v1.0.3","v2.0.0","v2.0.1","v2.0.2","v3.0.0","v3.0.1","v3.0.2","v3.0.3","v3.0.4","v3.0.5","v3.1.0","v3.1.1","v3.2.0","v3.2.1","v3.2.10","v3.2.11","v3.2.12","v3.2.13","v3.2.2","v3.2.3","v3.2.4","v3.2.5","v3.2.6","v3.2.7","v3.2.8","v3.2.9","v3.3.0","v3.3.1","v3.3.2","v3.3.3","v3.3.4"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-32141.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
