CVE-2026-25478 Litestar has a CORS origin allowlist bypass due to unescaped regex metacharacters in allowed origins
Litestar is an Asynchronous Server Gateway Interface ASGI framework. Prior to 2.20.0, CORSConfig.allowedoriginsregex is constructed using a regex built from configured allowlist values and used with fullmatch for validation. Because metacharacters are not escaped, a malicious origin can match...
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...
