{"id":"UBUNTU-CVE-2026-29062","details":"jackson-core contains core low-level incremental (\"streaming\") parser and generator abstractions used by Jackson Data Processor. From version 3.0.0 to before version 3.1.0, the UTF8DataInputJsonParser, which is used when parsing from a java.io.DataInput source, bypasses the maxNestingDepth constraint (default: 500) defined in StreamReadConstraints. A similar issue was found in ReaderBasedJsonParser. This allows a user to supply a JSON document with excessive nesting, which can cause a StackOverflowError when the structure is processed, leading to a Denial of Service (DoS). This issue has been patched in version 3.1.0.","modified":"2026-06-30T18:17:46.614308530Z","published":"2026-03-06T08:16:00Z","upstream":["CVE-2026-29062"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-29062"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-29062"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-core/commit/8b25fd67f20583e75fb09564ce1eaab06cd5a902"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-core/pull/1554"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-core/security/advisories/GHSA-6v53-7c9g-w56r"}],"affected":[{"package":{"name":"jackson-core","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/jackson-core?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.2-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libjackson2-core-java","binary_version":"2.4.2-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29062.json"}},{"package":{"name":"jackson-core","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/jackson-core?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.8.6-1","2.9.1-1","2.9.4-1","2.9.8-3~18.04"],"ecosystem_specific":{"binaries":[{"binary_version":"2.9.8-3~18.04","binary_name":"libjackson2-core-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29062.json"}},{"package":{"name":"jackson-core","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/jackson-core?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.9.8-3","2.10.0-1","2.10.1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.10.1-1","binary_name":"libjackson2-core-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29062.json"}},{"package":{"name":"jackson-core","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/jackson-core?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.12.1-1","2.13.0-1","2.13.0-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.13.0-2","binary_name":"libjackson2-core-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29062.json"}},{"package":{"name":"jackson-core","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/jackson-core?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.14.1-1","binary_name":"libjackson2-core-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29062.json"}},{"package":{"name":"jackson-core","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/jackson-core?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjackson2-core-java","binary_version":"2.14.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29062.json"}},{"package":{"name":"jackson-core","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/jackson-core?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.1-1","2.14.1-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.14.1-1build1","binary_name":"libjackson2-core-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-29062.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
