CVE-2026-25479
Litestar is an Asynchronous Server Gateway Interface ASGI framework. Prior to 2.20.0, in litestar.middleware.allowedhosts, allowlist entries are compiled into regex patterns in a way that allows regex metacharacters to retain special meaning e.g., . matches any character. This enables a bypass...
CVE-2026-25478
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...
