| 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. |

Workarounds
CNA: Until a fixed release is available, restrict HTTPRoute creation and modification for routes attached to the shared Gateway, and review or remove routes with match values that trigger the predicate injection. Where possible, enforce authentication and rate limiting at the backend as additional controls. An admission policy could reject confirmed exploit patterns, but validate it against legitimate routes; Gateway API match values can contain special characters. These measures reduce exposure but do not fix the shim. The backend and admission-policy measures are compensating controls; their effectiveness depends on the deployment and the specific route behavior
