{"id":"UBUNTU-CVE-2026-100352","details":"kin-openapi is a Go project for handling OpenAPI files. Prior to 0.148.0, the OpenAPI 3.1 validation path passes YAML NaN and infinity numeric values to santhosh-tekuri/jsonschema v6.0.2 without applying kin-openapi's existing finite-number guards. A remote unauthenticated client can send an application/yaml or application/x-yaml request body containing .nan, .inf, or -.inf to an operation with a numeric constraint, causing the dependency to create and dereference a nil big.Rat during ValidateRequest. Standard net/http servers recover the panic per connection, while other hosts or application goroutines may terminate the process. This issue is fixed in version 0.148.0.","modified":"2026-10-17T12:58:40.586695945Z","published":"2026-10-16T00:00:00Z","upstream":["CVE-2026-100352"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-100352"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-100352"},{"type":"REPORT","url":"https://github.com/getkin/kin-openapi/security/advisories/GHSA-rj39-cv6w-8wv7"},{"type":"REPORT","url":"https://github.com/getkin/kin-openapi/commit/4487f198ab8be0c37d6ca72c54f5dca4dc25270e"},{"type":"REPORT","url":"https://github.com/getkin/kin-openapi/commit/4487f198ab8be0c37d6ca72c54f5dca4dc25270e"},{"type":"REPORT","url":"https://github.com/getkin/kin-openapi/releases/tag/v0.148.0"}],"affected":[{"package":{"name":"golang-github-getkin-kin-openapi","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/golang-github-getkin-kin-openapi?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.32.0-2","0.80.0-1","0.85.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-getkin-kin-openapi-dev","binary_version":"0.85.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-100352.json"}},{"package":{"name":"golang-github-getkin-kin-openapi","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-getkin-kin-openapi?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.117.0-1","0.120.0-1","0.122.0-3","0.123.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-getkin-kin-openapi-dev","binary_version":"0.123.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-100352.json"}},{"package":{"name":"golang-github-getkin-kin-openapi","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/golang-github-getkin-kin-openapi?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.124.0-1","0.135.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-getkin-kin-openapi-dev","binary_version":"0.135.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-100352.json"}},{"package":{"name":"golang-github-getkin-kin-openapi","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/golang-github-getkin-kin-openapi?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.124.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-getkin-kin-openapi-dev","binary_version":"0.124.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-100352.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:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
