CVE-2025-64062 — Primakon Project Contract Management security vulnerability

High CVSS 8.8

The Primakon Pi Portal 1.0.18 /api/V2/pp_users?email endpoint is used for user data filtering but lacks proper server-side validation against the authenticated session. By manipulating the email parameter to an arbitrary value (e.g., otheruser@user.com), an attacker can assume the session and gain full access to the target user's data and privileges. Also, if the email parameter is left blank, the application defaults to the first user in the list, who is typically the application administrator, resulting in an immediate Privilege Escalation to the highest level.

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.
