CVE-2026-108334

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 o...
