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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-100352)\n\nAffected packages:\n\n- `github.com/getkin/kin-openapi < 0.148.0`\n\nPatched in:\n\n- `github.com/getkin/kin-openapi 0.148.0`\n\nSource: https://github.com/advisories/GHSA-rj39-cv6w-8wv7\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Red Hat Hardened Images · no fix planned: Red Hat Hardened Images · updated 2026-10-20 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-100352.json)\n- **RHSA-2026:85266** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-10-19 · [advisory](https://access.redhat.com/errata/RHSA-2026:85266)\n- **RHSA-2026:82637** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-10-14 · [advisory](https://access.redhat.com/errata/RHSA-2026:82637)","depth":"midnight","depthScore":53,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":225360,"id":"CVE-2026-100352","ts":1792468354045,"field":"exploit_available","old":"false","new":"true"}]}
