Short explanation
Between versions 0.136.0 and 0.149.0 of kin-openapi, an incomplete fix in openapi3filter lacks nil-items guards for array schemas, allowing remote denial of service.
Unauthenticated remote attackers can trigger application crashes and denial of service conditions by submitting specially crafted requests.
What should be done?
- Update the kin-openapi library or follow vendor advisories
Chain of evidence and sources
kin-openapi projesinin 0.136.0 ile 0.149.0 sürümleri arasında üç decoder yolunda nil-items koruması eksiktir.
Kimliği doğrulanmamış uzak bir istemci, dizi parametreleri veya form gövdeleri aracılığıyla deterministik bir nil-pointer panic tetikleyebilir.
Show the technical text from the sources
kin-openapi is a Go project for handling OpenAPI files. From 0.136.0 until 0.149.0, three openapi3filter decoder paths that were missed by the fix for GHSA-p6wj-qrr4-pgh5 lack a nil-items guard for legal OpenAPI 3.1 array schemas. An unauthenticated remote client can trigger a deterministic nil-pointer panic through an array query parameter, a deepObject query parameter containing an array property, or an application/x-www-form-urlencoded request body whose array property appears inside an allOf, anyOf, or oneOf subschema. The query and composed-body paths reach urlValuesDecoder.parseArray, while the deepObject path reaches buildResObj, and all pass a nil items schema into code that dereferences it. This issue is fixed in version 0.149.0.
