- Summary
- [none]
- Details
-
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 unexpectedly. The check relies on allowedoriginsregex.fullmatch(origin). This vulnerability is fixed in 2.20.0.
