How CVE-2025-32928 Works
CVE-2025-32928 is a critical deserialization vulnerability in ThemeGoods Altair (versions up to 5.2.2) that allows remote attackers to inject malicious objects via untrusted data. The flaw occurs when the application deserializes user-supplied input without proper validation, enabling arbitrary code execution or privilege escalation. Attackers exploit insecure PHP object deserialization by crafting a payload that triggers unintended class instantiation or method execution, leading to full system compromise.
DailyCVE Form

Version: ≤ 5.2.2
Vulnerability: Object Injection
Severity: Critical
Date: 05/29/2025
Prediction: Patch by 06/15/2025
What Undercode Say:
Exploit Analysis:
1. Payload Crafting:
$payload = serialize(new MaliciousClass());
2. Trigger via HTTP:
curl -X POST -d "data=$payload" http://target/wp-content/plugins/altair/vuln_endpoint.php
Protection Commands:
1. Immediate Mitigation:
chmod -R 750 /wp-content/plugins/altair/
2. WAF Rule:
location ~ /altair/ { deny all; }
Code Fix (Patch Workaround):
if (!is_trusted_source($_POST['data'])) {
die("Invalid input");
}
$data = json_decode($_POST['data'], true); // Use JSON instead of unserialize()
Detection Script:
import requests
def check_vuln(url):
res = requests.post(url, data={"data":"O:8:\"stdClass\":0:{}}"})
return "unserialize()" in res.text
Post-Patch Audit:
grep -r "unserialize(" /var/www/html/
Log Analysis:
tail -f /var/log/apache2/access.log | grep "altair.POST"
Impact Metrics:
- RCE Likelihood: High
- Exploit Complexity: Low
- Patch Urgency: Immediate
