一、漏洞信息
漏洞编号：CVE-2026-77354
漏洞归属组件：kin-openapi
漏洞归属分支：默认分支
漏洞归属的版本：v0.127.0
漏洞修复版本: 0.142.0
CVSS分值：
BaseScore： N/A None
Vector： N/A
漏洞简述：
kin-openapi is a Go project for handling OpenAPI files. From 0.124.0 until 0.142.0, openapi3filter.sliceMapToSlice in openapi3filter/req_resp_decoder.go converts attacker-controlled sparse indexes from a deepObject query parameter into a dense slice by allocating entries from zero through the largest supplied index, after which buildResObj creates another slice of the same length. This allocation occurs before schema validation, so maxItems does not prevent it. An unauthenticated client can send a small query such as param[items][50000000]=x to an endpoint whose deepObject schema contains an array, forcing multi-gigabyte heap allocation and causing an OOM kill or restart loop. Other request-body encodings and styled parameters that do not produce bracketed integer indexes are not affected. This issue is fixed in version 0.142.0.
