CVE-2026-41464 — ProjeQtor security vulnerability

High CVSS 7.1

ProjeQtor versions 7.0 through 12.4.3 contain a missing authorization vulnerability in the objectDetail.php endpoint that allows authenticated users with guest-level privileges to retrieve sensitive data belonging to other users including password hashes and API keys. Attackers can bypass access controls by directly accessing the endpoint without ownership or role-based validation to extract administrator credentials and perform privilege escalation.

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.
