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

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.
