0 CVE-2026-25478 is a high-severity vulnerability in the litestar ASGI framework versions prior to 2.20.0. It arises from improper construction of the allowed_origins_regex used for CORS origin validation, where metacharacters in the allowlist are not escaped. This flaw allows malicious origins to bypass the intended restrictions, potentially enabling cross-domain attacks. Exploitation requires user interaction but no authentication, and it can lead to a breach of confidentiality by exposing sensitive data to untrusted domains. The vulnerability affects web applications using litestar for asynchronous server gateway interfaces, particularly those relying on CORS for security. Although no known exploits are currently in the wild, the vulnerability's nature and CVSS score of 7.4 indicate a significant risk. European organizations using litestar in web services should prioritize upgrading to version 2. Join the discussion | CVE Database V5 | 02/09/2026, 18:46:56 UTC Added: 02/09/2026, 19:31:19 UTC |
