How the CVE Works
CVE-2025-32927 exploits insecure deserialization in Chimpstudio FoodBakery (versions up to 3.3), allowing attackers to inject malicious objects via untrusted data. When user-supplied input is deserialized without proper validation, arbitrary code execution or object injection occurs. Attackers craft serialized payloads to trigger unintended behaviors, such as remote command execution or file system access. The lack of input sanitization enables this exploit, often leading to full system compromise.
DailyCVE Form
Platform: Chimpstudio FoodBakery
Version: ≤ 3.3
Vulnerability: Insecure Deserialization
Severity: Critical
Date: 05/29/2025
Prediction: Patch expected by 06/15/2025
What Undercode Say:
Analytics:
- Exploitability: High (PoC likely public soon)
- Affected Systems: WordPress sites using FoodBakery plugin
- Attack Vector: Remote via crafted HTTP requests
Exploit Command (Example):
curl -X POST -d "malicious_serialized_data" http://target.com/foodbakery-endpoint
Protection Steps:
1. Immediate Mitigation: Disable FoodBakery until patch.
2. WAF Rules: Block suspicious serialized data patterns.
- Code Fix: Replace unsafe `unserialize()` with JSON or strict validation.
Sample PHP Sanitization:
if (!is_valid_serialized($input)) {
die("Invalid data");
}
function is_valid_serialized($data) {
return @unserialize($data) !== false;
}
Log Monitoring:
grep "unserialize.foodbakery" /var/log/apache2/error.log
Patch Verification:
wp plugin list | grep "foodbakery" | awk '{print $2}'
Expected Post-Patch Behavior:
- Serialized data requires cryptographic signatures.
- Restricted class types during deserialization.
Impact Reduction:
- Use PHP’s `allowed_classes` in
unserialize(). - Deploy runtime integrity checks (e.g., PHPIDS).
