    • @neverendingsupport/angular-upgrade@9.1.13-angular-9.1.23
    • @neverendingsupport/zone.js@0.10.3-angular-9.1.23

Security Fixes

  • core:
    • Validate security-sensitive attributes in i18n bindings.
    • Disallow event attribute bindings in host bindings unconditionally.
  • platform-server: Add allowedHosts option to renderModule and renderModuleFactory.
    • This fixes a high-severity Server-Side Request Forgery (SSRF) vulnerability (CVE-2026-46417).

Breaking Changes

platform-server
  • Add allowedHosts option to renderModule and renderModuleFactory:
    When url is an absolute URL, its hostname is now validated against the new allowedHosts option, mitigating Server-Side Request Forgery (SSRF) and Host Header Injection attacks. This validation applies to both rendering entry points (renderModule and renderModuleFactory). Because allowedHosts defaults to an empty allow-list, any absolute URL now throws at bootstrap unless allowedHosts is configured. Relative URLs (e.g. /path) are unaffected.
    To pass validation, configure allowedHosts with the hostnames you serve (exact hostnames, *.example.com wildcards, or * to allow all).

v9.1.22 - April 9, 2026

Notes

  • Full package name(s) and version(s):

    • @neverendingsupport/angular-upgrade@9.1.13-angular-9.1.22
    • @neverendingsupport/zone.js@0.10.3-angular-9.1.22

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.
