{"id":"UBUNTU-CVE-2026-54518","details":"jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.21.0 until 2.21.4 and 3.1.4, UnwrappedPropertyHandler.processUnwrappedCreatorProperties() replays buffered JSON into creator parameters but never consults prop.visibleInView(activeView). The normal property-based creator path gates creator properties on the active view, but this unwrapped-creator replay path bypasses that check, so a constructor parameter annotated with both @JsonView(AdminView.class) and @JsonUnwrapped is populated from attacker JSON even when a more restrictive view is active. This vulnerability is fixed in 2.21.4 and 3.1.4.","modified":"2026-06-25T17:17:44Z","published":"2026-06-23T22:16:00Z","upstream":["CVE-2026-54518"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-54518"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-54518"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-rcqc-6cw3-h962"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/pull/5971"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/pull/5973"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/commit/721fa07ebbd4aab4a659a1a68940878315c3e341"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/commit/d633bc038f200c1397c07f1a2b46f58e72c91eea"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/commit/721fa07ebbd4aab4a659a1a68940878315c3e341"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/commit/d633bc038f200c1397c07f1a2b46f58e72c91eea"}],"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-2026-54518.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_version":"2.4.2-3ubuntu0.1~esm2","binary_name":"libjackson2-databind-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54518.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-2026-54518.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_version":"2.10.2-1","binary_name":"libjackson2-databind-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54518.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_name":"libjackson2-databind-java","binary_version":"2.13.0-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54518.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-2026-54518.json"}},{"package":{"name":"jackson-databind","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/jackson-databind?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.0+ds-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.14.0+ds-1","binary_name":"libjackson2-databind-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54518.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_version":"2.14.0+ds-1build1","binary_name":"libjackson2-databind-java"}]},"database_specific":{"source":"https://github.com/canonical/ubun
