UBUNTU-CVE-2026-46644 0 A vulnerability exists in symfony/polyfill-intl-idn versions from 1.17.1 up to 1.38.1 where the library accepts xn-- labels with empty or ASCII-only Punycode payloads. This occurs because Idn::process() does not enforce the UTS #46 revision 33 requirement that decoded ACE labels contain at least one non-ASCII code point. This flaw can cause originally unequal domain names to be treated as equal, potentially leading to blacklist bypassing, inconsistent URL parsing, and server-side request forgery in applications relying on this polyfill for hostname canonicalization or comparison. The issue is fixed in version 1.38.1. Join the discussion | GCVE Database | 07/14/2026, 21:16:00 UTC Added: 07/16/2026, 10:38:18 UTC |
