Security Fixes

  • core: Block creation of sensitive URI attributes from ICU messages.
    • This fixes a high-severity Cross-Site Scripting (XSS) vulnerability (CVE-2026-27970).

Breaking Changes

core
  • Block creation of sensitive URI attributes from ICU messages:
    Translators can no longer introduce URI attributes—attribute values are blocked to avoid malicious links, and sanitization now relies on an allowlist of known attributes (still sanitizing URI ones). Translated ICU content keeps only recognized attributes and drops everything else.
