Summary

The getkin kin-openapi package and the Go module github.com/getkin/kin-openapi are affected before 0.145.0. The openapi3.Loader dereferences a nil schema value while resolving a self-referential additionalProperties JSON Reference, which is CWE-476. An attacker who supplies a crafted OpenAPI document to LoadFromData, LoadFromFile, or LoadFromURI can crash the loading process.

Description from the CNA

kin-openapi is a Go project for handling OpenAPI files. Prior to 0.145.0, openapi3.Loader can dereference a nil SchemaRef.Value while resolving a self-referential additionalProperties JSON Reference such as a schema that points to its own additionalProperties member. Loading an attacker-controlled OpenAPI document through LoadFromData, LoadFromFile, or LoadFromURI reaches resolveComponent before document validation and can panic the loading process. Resolved additionalProperties schemas and ordinary recursive schemas do not take the vulnerable nil-value path. This issue is fixed in version 0.145.0.
