Search: CVE-2026-100348

CVE-2026-100348 is a medium severity vulnerability in the kin-openapi library's openapi3 loader component. It involves a NULL pointer dereference in the resolveComponent function when processing additionalProperties in schema references. This occurs because the code dereferences c.Value.AdditionalProperties without checking if c.Value is nil, leading to a panic during loading of crafted OpenAPI documents. The issue affects kin-openapi versions prior to 0.145.0 and can cause denial of service by crashing applications that load untrusted OpenAPI specifications.
