AI Analysis

Impact

The vulnerability in Shopizer allows a logged‑in customer to submit product reviews that are attributed to another customer by including a customerId field in the review payload. This flaw permits an attacker with a valid account to forge review authorship and alter the perception of product ratings. The weakness is an authorization bypass (CWE‑639) because the system does not verify that the supplied customerId matches the authenticated user, undermining the integrity of user‑generated content.

Affected Systems

Shopizer e‑commerce platform, versions 3.2.5 and earlier, carry the affected code that accepts a customerId when creating a review. The bug exists in all releases prior to 3.2.6.

Risk and Exploitability

With a CVSS score of 5.3 the flaw is rated medium severity. An attacker only needs a legitimate Shopizer account and can construct a POST request to /api/v1/auth/products/{id}/reviews with any customerId, allowing abuse of review authorship. The EPSS score is below 1 %, indicating a very low exploitation probability, and the vulnerability is not listed in the CISA KEV catalog. The impact is primarily data integrity and potential reputation damage, not system compromise.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade to Shopizer 3.2.6 or later, where the review API no longer accepts an external customerId value.
  • Configure the review service to validate that the customerId supplied in the payload equals the id of the authenticated user; reject any mismatched value.
  • Enable monitoring or logging of review creation endpoints to detect anomalous review authorship patterns and respond promptly to abuse.
