{"id":"UBUNTU-CVE-2026-54515","details":"jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.8.0 until 2.18.9, 2.21.5, and 3.1.4, in BeanDeserializerBase.createContextual(), per-property @JsonIgnoreProperties exclusions are applied by _handleByNameInclusion(), producing a contextual deserializer whose BeanPropertyMap has the ignored properties removed. The subsequent per-property case-insensitivity block (triggered by @JsonFormat(ACCEPT_CASE_INSENSITIVE_PROPERTIES)) rebuilds from this._beanProperties (the original, unfiltered map) instead of contextual._beanProperties, then overwrites the filtered map — restoring every property _handleByNameInclusion had just removed. The ignored property becomes writable again. This vulnerability is fixed in 2.18.9, 2.21.5, and 3.1.4.","modified":"2026-06-25T17:17:44Z","published":"2026-06-23T21:17:00Z","upstream":["CVE-2026-54515"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-54515"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-54515"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-5jmj-h7xm-6q6v"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/issues/5962"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/pull/5964"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/commit/0e1b0b211f7a53baa62ba2f4c9bd006c7bf4d5fa"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/commit/0e1b0b211f7a53baa62ba2f4c9bd006c7bf4d5fa"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/issues/5964"}],"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-2026-54515.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-2026-54515.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_version":"2.9.8-1~18.04","binary_name":"libjackson2-databind-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54515.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-2026-54515.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-2026-54515.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-2026-54515.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_name":"libjackson2-databind-java","binary_version":"2.14.0+ds-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54515.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-2026-54515.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC
