Eases web-request routing, handling, and response as a half-way front, half-way page controller. Implemented with specific emphasis on enabling easy unit/integration testing that doesn't require a browser.

Security Fix(es):

The actionpack ruby gem before 6.1.3.2, 6.0.3.7, 5.2.4.6, 5.2.6 suffers from a possible denial of service vulnerability in the Token Authentication logic in Action Controller due to a too permissive regular expression. Impacted code uses authenticate_or_request_with_http_token or authenticate_with_http_token for request authentication.(CVE-2021-22904)

Severity

7.5 (High)
