DescriptionNVD

Litestar is an Asynchronous Server Gateway Interface (ASGI) framework. Prior to 2.20.0, 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 URL to serve cached responses of another (cache poisoning/mixup). This vulnerability is fixed in 2.20.0.

AnalysisAI

Cache poisoning in Litestar before 2.20.0 allows unauthenticated remote attackers to exploit improper Unicode normalization in the FileStore cache backend to create collisions between cache keys, enabling one URL to serve another URL's cached responses. Public exploit code exists for this vulnerability. …
