{"id":"UBUNTU-CVE-2026-59889","details":"jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.18.0 until 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1, UnwrappedPropertyHandler.processUnwrapped() replays buffered JSON for a @JsonUnwrapped property and calls prop.deserializeAndSet() without a prop.visibleInView(ctxt.getActiveView()) guard, allowing a property annotated with both @JsonView and @JsonUnwrapped to be written from attacker JSON under a less-privileged active view. This issue is fixed in versions 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1.","modified":"2026-07-15T19:47:52.037852464Z","published":"2026-07-14T21:17:00Z","upstream":["CVE-2026-59889"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-59889"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-59889"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-5gvw-p9qm-jgwh"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/issues/6060"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/pull/6056"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/commit/d627a8a86fcb062429282f79f3f256f181ed2c7b"}],"affected":[{"package":{"name":"jackson-databind","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/jackson-databind?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.2-1","2.2.2-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjackson2-databind-java","binary_version":"2.2.2-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59889.json"}},{"package":{"name":"jackson-databind","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/jackson-databind?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.2-2","2.4.2-3","2.4.2-3ubuntu0.1~esm1","2.4.2-3ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"libjackson2-databind-java","binary_version":"2.4.2-3ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59889.json"}},{"package":{"name":"jackson-databind","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/jackson-databind?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.8.6-1","2.9.1-1","2.9.4-1","2.9.5-1","2.9.8-1~18.04"],"ecosystem_specific":{"binaries":[{"binary_name":"libjackson2-databind-java","binary_version":"2.9.8-1~18.04"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59889.json"}},{"package":{"name":"jackson-databind","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/jackson-databind?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.9.9.3-1","2.10.0-2","2.10.1-1","2.10.2-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjackson2-databind-java","binary_version":"2.10.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59889.json"}},{"package":{"name":"jackson-databind","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/jackson-databind?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.12.1-1","2.12.5-1","2.13.0-1","2.13.0-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.13.0-2","binary_name":"libjackson2-databind-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59889.json"}},{"package":{"name":"jackson-databind","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/jackson-databind?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjackson2-databind-java","binary_version":"2.14.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59889.json"}},{"package":{"name":"jackson-databind","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/jackson-databind?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.0+ds-1","2.14.0+ds-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjackson2-databind-java","binary_version":"2.14.0+ds-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59889.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
