{"id":"UBUNTU-CVE-2022-1471","details":"SnakeYaml's Constructor() class does not restrict types which can be instantiated during deserialization. Deserializing yaml content provided by an attacker can lead to remote code execution. We recommend using SnakeYaml's SafeConsturctor when parsing untrusted content to restrict deserialization. We recommend upgrading to version 2.0 and beyond.","modified":"2025-09-08T16:49:31Z","published":"2022-12-01T11:15:00Z","upstream":["CVE-2022-1471"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-1471"},{"type":"REPORT","url":"https://github.com/google/security-research/security/advisories/GHSA-mjmj-j48q-9wg2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-1471"}],"affected":[{"package":{"name":"snakeyaml","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/snakeyaml@1.12-2ubuntu0.14.04.1~esm2?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12-2","1.12-2ubuntu0.14.04.1~esm1","1.12-2ubuntu0.14.04.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.12-2ubuntu0.14.04.1~esm2","binary_name":"libyaml-snake-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-1471.json"}},{"package":{"name":"snakeyaml","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/snakeyaml@1.12-2ubuntu0.16.04.1~esm2?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12-2","1.12-2ubuntu0.16.04.1~esm1","1.12-2ubuntu0.16.04.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.12-2ubuntu0.16.04.1~esm2","binary_name":"libyaml-snake-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-1471.json"}},{"package":{"name":"snakeyaml","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/snakeyaml@1.23-1+deb10u1ubuntu0.1~esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.17-1","1.19-1","1.20-1","1.23-1~18.04","1.23-1+deb10u1build0.18.04.1","1.23-1+deb10u1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.23-1+deb10u1ubuntu0.1~esm1","binary_name":"libyaml-snake-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-1471.json"}},{"package":{"name":"snakeyaml","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/snakeyaml@1.25+ds-2ubuntu0.1+esm1?arch=source&distro=esm-apps/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.23-1","1.25+ds-2","1.25+ds-2ubuntu0.1","1.25+ds-2ubuntu0.1+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.25+ds-2ubuntu0.1+esm1","binary_name":"libyaml-snake-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-1471.json"}},{"package":{"name":"snakeyaml","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/snakeyaml@1.29-1ubuntu0.22.04.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.28-1","1.29-1","1.29-1ubuntu0.22.04.1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.29-1ubuntu0.22.04.1","binary_name":"libyaml-snake-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-1471.json"}},{"package":{"name":"snakeyaml","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/snakeyaml@1.33-2?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.33-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.33-2","binary_name":"libyaml-snake-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-1471.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L"},{"type":"Ubuntu","score":"medium"}]}
