{"id":"UBUNTU-CVE-2026-77310","details":"jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. Prior to versions 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1 on their respective release lines, the java.net.InetAddress branch of FromStringDeserializer.Std._deserialize() calls InetAddress.getByName() on attacker-controlled input, causing eager DNS resolution during deserialization and enabling DNS-based server-side request forgery and internal-host enumeration. This issue is fixed in versions 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1.","modified":"2026-09-02T19:42:23.352549812Z","published":"2026-08-24T20:17:00Z","upstream":["CVE-2026-77310"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-77310"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-77310"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-vvgp-rfg2-7rr6"},{"type":"REPORT","url":"https://github.com/FasterXML/jackson-databind/commit/2fc7bd9057dd051d7dea0e5fcad89822d0fa5ebd"}],"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_version":"2.2.2-1ubuntu0.1~esm1","binary_name":"libjackson2-databind-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-77310.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-2026-77310.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-2026-77310.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-2026-77310.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-2026-77310.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-2026-77310.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/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-77310.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
