CVE-2026-94104
HighCVSS 8.8Summary
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.
Risk Assessment
An attacker with limited access could upload and execute malicious PHP code, leading to full server compromise and data exposure. The risk is high because only view-only access is required.
Recommendation
Implement file extension validation in the multi() endpoint, restrict the ability to upload executable files, and update NivoCart to a patched version.

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.
