"CVE-2026-54614"
],
"details": "### Impact\n\nThe `MailPreview` feature of debugkit is vulnerable to arbitrary constructor execution. For an application to be vulnerable the following conditions must be true:\n\n1. `debug` mode must be enabled.\n2. The hostname must match a 'local' domain or be in an allowlist.\n\n### Patches\n5.2.4 and 4.10.3 contain patches for this issue.\n\n### Workarounds\nEnsure that debugkit is only part of your development dependencies, and that debug mode is disabled in production environments.",
