CVE-2026-108334— Github.com/kuadrant/kuadrant-operator/internal/wasm: github.com/rh-api-management/rhcl-operator-product-build/kuadrant-operator: kuadrant-operator: crafted httproute match values can bypass gateway policy overrides

Quick assessment

Affected
Red Hat Red Hat Connectivity Link 1.4
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Kuadrant 操作器所使用的内部 WebAssembly（WASM）存根（shim）中发现了一个漏洞。在生成用于判断是否应启用网关级别的身份验证和速率限制策略的 CEL 谓词时，该存根未能正确转义来自 HTTPRoute 匹配字段的值。能够创建或修改附加到共享网关的 HTTPRoute 的用户，可以通过提供精心构造的路径、头部或查询匹配值，使谓词跳过这些安全检查。尽管请求未通过身份验证和速率限制检查，它仍会被转发至该路由的后端服务。

Vulnerability Title
Github.com/kuadrant/kuadrant-operator/internal/wasm: github.com/rh-api-management/rhcl-operator-product-build/kuadrant-operator: kuadrant-operator: crafted httproute match values can bypass gateway policy overrides
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the internal WebAssembly (WASM) shim used by the Kuadrant operator. When generating the CEL predicate that determines whether Gateway-level authentication and rate limiting should run, the shim does not correctly escape values from HTTPRoute match fields. A user who can create or modify an HTTPRoute attached to a shared Gateway can provide a crafted path, header, or query match value that causes the predicate to skip those checks. The request is still forwarded to the route’s backend.
