CVE intelligence and bounded remediation
CVE-2026-28515 — openDCIM version 23.04, through commit 4467e9c4, contains a missing authorization vulnerability in install.php and container-install.php
openDCIM version 23.04, through commit 4467e9c4, contains a missing authorization vulnerability in install.php and container-install.php. The installer and upgrade handler expose LDAP configuration functionality without enforcing application role checks. Any authenticated user can access this functionality regardless of assigned privileges. In deployments where REMOTE_USER is set without authentication enforcement, the endpoint may be accessible without credentials. This allows unauthorized modification of application configuration.

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.
