{"id":"CVE-2022-42003","aliases":["GHSA-jjjh-jjxp-wpff"],"url":"https://o3.security/vulnerability/CVE-2022-42003","summary":"Uncontrolled Resource Consumption in Jackson-databind","details":"In FasterXML jackson-databind 2.4.0-rc1 until 2.12.7.1 and in 2.13.x before 2.13.4.2 resource exhaustion can occur because of a lack of a check in primitive value deserializers to avoid deep wrapper array nesting, when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. This was patched in 2.12.7.1, 2.13.4.2, and 2.14.0.\n\nCommits that introduced vulnerable code are \nhttps://github.com/FasterXML/jackson-databind/commit/d499f2e7bbc5ebd63af11e1f5cf1989fa323aa45, https://github.com/FasterXML/jackson-databind/commit/0e37a39502439ecbaa1a5b5188387c01bf7f7fa1, and https://github.com/FasterXML/jackson-databind/commit/7ba9ac5b87a9d6ac0d2815158ecbeb315ad4dcdc.\n\nFix commits are https://github.com/FasterXML/jackson-databind/commit/cd090979b7ea78c75e4de8a4aed04f7e9fa8deea and https://github.com/FasterXML/jackson-databind/commit/d78d00ee7b5245b93103fef3187f70543d67ca33.\n\nThe `2.13.4.1` release does fix this issue, however it also references a non-existent jackson-bom which causes build failures for gradle users. See https://github.com/FasterXML/jackson-databind/issues/3627#issuecomment-1277957548 for details. This is fixed in `2.13.4.2` which is listed in the advisory metadata so that users are not subjected to unnecessary build failures","published":"2022-10-02T00:00:00Z","modified":"2026-10-22T07:12:51.744710603Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.02779,"percentile":0.85688,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":2,"affectedPackages":[{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","fixedVersion":"2.12.7.1"},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","fixedVersion":"2.13.4.2"}],"fix":{"url":"https://github.com/FasterXML/jackson-databind/commit/d78d00ee7b5245b93103fef3187f70543d67ca33","label":"FasterXML/jackson-databind@d78d00e"},"references":[{"type":"WEB","url":"https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=51020"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/42xxx/CVE-2022-42003.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-42003"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202210-21"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20221124-0004/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2022/dsa-5283"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/issues/3590"},{"type":"FIX","url":"https://github.com/FasterXML/jackson-databind/commit/d78d00ee7b5245b93103fef3187f70543d67ca33"},{"type":"ARTICLE","url":"https://lists.debian.org/debian-lts-announce/2022/11/msg00035.html"},{"type":"WEB","url":"https://github.com/FasterXML/jackson-databind/issues/3627"},{"type":"WEB","url":"https://github.com/FasterXML/jackson-databind/commit/0e37a39502439ecbaa1a5b5188387c01bf7f7fa1"},{"type":"WEB","url":"https://github.com/FasterXML/jackson-databind/commit/2c4a601c626f7790cad9d3c322d244e182838288"},{"type":"WEB","url":"https://github.com/FasterXML/jackson-databind/commit/7ba9ac5b87a9d6ac0d2815158ecbeb315ad4dcdc"},{"type":"WEB","url":"https://github.com/FasterXML/jackson-databind/commit/cd090979b7ea78c75e4de8a4aed04f7e9fa8deea"},{"type":"WEB","url":"https://github.com/FasterXML/jackson-databind/commit/d499f2e7bbc5ebd63af11e1f5cf1989fa323aa45"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20221124-0004"},{"type":"WEB","url":"https://github.com/FasterXML/jackson-databind/compare/jackson-databind-2.13.4.1...jackson-databind-2.13.4.2"},{"type":"WEB","url":"https://github.com/FasterXML/jackson-databind/commits/jackson-databind-2.4.0-rc1?after=75b97b8519f0d50c62523ad85170d80a197a2c86+174&branch=jackson-databind-2.4.0-rc1&qualified_name=refs%2Ftags%2Fjackson-databind-2.4.0-rc1"},{"type":"WEB","url":"https://github.com/FasterXML/jackson-databind/blob/2.13/release-notes/VERSION-2.x"},{"type":"PACKAGE","url":"https://github.com/FasterXML/jackson-databind"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-22T07:12:51.744710603Z"}}
