CVE-2026-28490: Authlib Internal Registry Unsafe Algorithm Lookupcve-2026-28490-authlib-internal-registry-unsafe-algorithm-lookup

This rule detects Authlib's internal pattern before CVE-2026-28490 was fixed, where an algorithm is retrieved from a registry without validating whether it is deprecated when an explicit whitelist config is missing. This allowed insecure algorithms like RSA1_5 and 'none' to be used by default.
