CVE-2023-28362: Rails Action Pack

Medium severity, CVSS 4.0. EPSS: 0.3% chance of exploitation in the next 30 days.

The redirect_to method in Rails allows provided values to contain characters which are not legal in an HTTP header value. This results in the potential for downstream services which enforce RFC compliance on HTTP response headers to remove the assigned Location header.

Affected products

• Rails Action Pack: from 7, before 7.0.5.1 (fixed in 7.0.5.1); from 6, before 6.1.7.4 (fixed in 6.1.7.4)
