CVE-2025-65276 — Henzljw Hashtech security vulnerability

Critical CVSS 9.8

An unauthenticated administrative access vulnerability exists in the open-source HashTech project (https://github.com/henzljw/hashtech) 1.0 thru commit 5919decaff2681dc250e934814fc3a35f6093ee5 (2021-07-02). Due to missing authentication checks on /admin_index.php, an attacker can directly access the admin dashboard without valid credentials. This allows full administrative control including viewing/modifying user accounts, managing orders, changing payments, and editing product listings. Successful exploitation can lead to information disclosure, data manipulation, and 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.
