CVE-2025-52920 — Innoshop through 0.4.1 allows Insecure Direct Object Reference (IDOR) at multiple places within the frontend shop

Medium CVSS 6.4

Innoshop through 0.4.1 allows Insecure Direct Object Reference (IDOR) at multiple places within the frontend shop. Anyone can create a customer account and easily exploit these. Successful exploitation results in disclosure of the PII of other customers and the deletion of their reviews of products on the website. To be specific, an attacker could view the order details of any order by browsing to /en/account/orders/_ORDER_ID_ or use the address and billing information of other customers by manipulating the shipping_address_id and billing_address_id parameters when making an order (this information is then reflected in the receipt). Additionally, an attacker could delete the reviews of other users by sending a DELETE request to /en/account/reviews/_REVIEW_ID.

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.
