CVE intelligence and bounded remediation

CVE-2024-27915 — Sulu is a PHP content management system

High CVSS 8.1

Sulu is a PHP content management system. Starting in verson 2.2.0 and prior to version 2.4.17 and 2.5.13, access to pages is granted regardless of role permissions for webspaces which have a security system configured and permission check enabled. Webspaces without do not have this issue. The problem is patched in versions 2.4.17 and 2.5.13. Some workarounds are available. One may apply the patch to `vendor/symfony/security-http/HttpUtils.php` manually or avoid installing `symfony/security-http` versions greater equal than `v5.4.30` or `v6.3.6`.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
