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...
CVE-2026-25479 Litestar has an AllowedHosts validation bypass due to unescaped regex metacharacters in configured host patterns
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...
