# 🧨 CVE-2025-32432 – Craft CMS Pre-auth RCE 🧨
### 🕵️ Overview
* **Severity**: Critical (CVSS Score: 10.0)
* **Type**: Remote Code Execution (RCE) via insecure deserialization
* **Affected Product**: Craft CMS
* **Authentication**: **None required** — attacker only needs a valid asset ID
---
### 📦 Affected Versions
* Craft CMS **3.x**: from 3.0.0-RC1 up to 3.9.14
* Craft CMS **4.x**: from 4.0.0-RC1 up to 4.14.14
* Craft CMS **5.x**: from 5.0.0-RC1 up to 5.6.16
---
### ✅ Fixed Versions
* **3.9.15**
* **4.14.15**
* **5.6.17**
---
### 🔬 Technical Details
* Vulnerability is in the endpoint: `/actions/assets/generate-transform`
* Attackers send a specially crafted **POST** request with a serialized PHP object that contains the `__class` property
* This triggers **unsafe deserialization**, which leads to **arbitrary code execution**
* Exploitable without authentication
---
### 🚨 Exploitation in the Wild
* **Actively exploited** by attackers in real-world attacks
* Threat actors (e.g., "Mimo" group) used it to drop **cryptominers**, **web shells**, and **proxyware**
* Thousands of Craft CMS instances are believed to be vulnerable, with hundreds confirmed compromised
---
### 🛡️ Mitigation Steps
1. **Update immediately** to one of the patched versions
2. If updating is not possible right away:
* Block POST requests to `/actions/assets/generate-transform` that contain `__class`
* Use Craft CMS’s security patching tools or plugins
3. If compromised:
* Take the server offline
* Remove any web shells or malicious files
* Rotate all secrets and credentials
* Force password resets for all users
* Audit logs for suspicious activity
---
### 🧪 Indicators of Compromise (IoCs)
* Suspicious POST requests to `/actions/assets/generate-transform`
* Payloads containing `__class` in the request body
* Unexpected or recently modified PHP files
* Unusual resource usage (e.g., high CPU from cryptominers)
