CVE-2026-94571: Improper Control of Generation of Code

In OpenStack Octavia before 18.0.1, the Amphora provider driver did not reject control characters in the L7 policy redirecturl and redirectprefix fields. The RFC 3986 URL validator percent-encodes control characters before validating, and thus newlines passed structural checks, but Octavia stored...
