GHSA-VXQX-RH46-Q2PG Litestar's FileStore key canonicalization collisions allow response cache mixup/poisoning (ASCII ord + Unicode NFKD)

Summary FileStore maps cache keys to filenames using Unicode NFKD normalization and ord substitution without separators, creating key collisions. When FileStore is used as response-cache backend, an unauthenticated remote attacker can trigger cache key collisions via crafted paths, causing one UR...
