Summary
NivoCart through 2.5.1 contains a missing authorization vulnerability in the download() action of account/order that allows unauthenticated attackers to retrieve guest order invoices by supplying an order_id. Attackers can iterate the order_id parameter, which matches guest orders stored with customer_id 0, to disclose guest names, addresses, telephone numbers, emails, purchased items, and totals.
Risk Assessment
Exposure of guest personal data and order details can lead to privacy breaches, identity theft, and regulatory consequences under GDPR.
Recommendation
Upgrade NivoCart beyond 2.5.1 or enforce authorization checks on the download() action and restrict access to guest order invoices.
Other vulnerabilities in NivoCart
See all- CVE-2026-111278Medium
NivoCart through 2.5.1 contains a CAPTCHA bypass vulnerability because the expected code is printed as plain text in the HTML. Unauthenticated attackers can fetch protected forms, extract the captcha_image value, and automate spam, registrations, reviews, and account deletion requests.
- CVE-2026-94107High
NivoCart through 2.4.0 contains a predictable password reset token vulnerability in the forgotten.php endpoint that generates recovery codes using substr(md5(mt_rand()), 0, 10). Attackers who know an administrator's email address can request a password reset and predict the token to gain administrative account access without rate limiting or expiration.
- CVE-2026-94105Medium
NivoCart through 2.4.0 contains a destructive configuration write vulnerability in the admin password reset controller that allows unauthenticated attackers to disable password recovery by supplying an invalid code parameter. Attackers can send a GET request with a missing or incorrect code to rewrite the config_password setting to 0, disabling self-service password recovery until an administrator manually re-enables it.
- CVE-2026-94104High
NivoCart through 2.4.0 contains an arbitrary file upload vulnerability in the File Manager multi() endpoint that fails to validate file extensions for new filenames or when the chunks parameter is 2 or higher. Attackers with view-only back-office access can upload PHP files to the web-accessible image/data/ directory and execute them for remote code execution.
