CVE-2026-108334 is a high-severity flaw (CVSS 7.4) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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 che
