{"id":"DEBIAN-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":"2026-10-25T17:00:06.847307503Z","published":"2026-10-15T16:17:31.307Z","upstream":["CVE-2026-100352"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-100352"}],"affected":[{"package":{"name":"golang-github-getkin-kin-openapi","ecosystem":"Debian:12","purl":"pkg:deb/debian/golang-github-getkin-kin-openapi?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.110.0-1","0.117.0-1","0.118.0-1","0.120.0-1","0.122.0-1","0.122.0-2","0.122.0-3","0.123.0-1","0.124.0-1","0.135.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-100352.json"}},{"package":{"name":"golang-github-getkin-kin-openapi","ecosystem":"Debian:13","purl":"pkg:deb/debian/golang-github-getkin-kin-openapi?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.124.0-1","0.135.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-100352.json"}},{"package":{"name":"golang-github-getkin-kin-openapi","ecosystem":"Debian:14","purl":"pkg:deb/debian/golang-github-getkin-kin-openapi?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.124.0-1","0.135.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-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"}]}
