Q1What is this vulnerability? (Essence + Consequences)
🚨 **Essence**: Livewire (Laravel full-stack framework) suffers from **Code Injection** due to improper handling of component property updates.…
🛡️ **Root Cause**: **CWE-94** (Code Injection). The vulnerability stems from how Livewire processes and updates component properties, failing to sanitize or validate inputs correctly before execution.
Q3Who is affected? (Versions/Components)
👥 **Affected**: All versions of **Livewire up to 3.6.3**. If you are running v3.6.3 or earlier, your application is vulnerable. 📦 Vendor: Livewire.
Q4What can hackers do? (Privileges/Data)
💀 **Attacker Capabilities**: Hackers can execute arbitrary commands on the server. This leads to full **system compromise**, data theft, and potential lateral movement within the network. ⚠️ High Privilege.
Q5Is exploitation threshold high? (Auth/Config)
🔓 **Exploitation Threshold**: **Low to Medium**. While some PoCs require the `APP_KEY` for full RCE, the vulnerability exists in the core property handling. Public scanners exist to detect vulnerable sites easily. 🎯
Q6Is there a public Exp? (PoC/Wild Exploitation)
🔥 **Public Exploits**: **YES**. Multiple PoCs are available: `Livepyre` (Synacktiv), Vulhub guides, and fast Python scanners (e.g., `Livewire2025CVE`). Wild exploitation is highly likely. 💣
Q7How to self-check? (Features/Scanning)
🔍 **Self-Check**: Use automated scanners like the Python tool from `z0d131482700x` to detect vulnerable Laravel Livewire v3 sites. Check your `composer.lock` for version < 3.6.4. 🧪
Q8Is it fixed officially? (Patch/Mitigation)
✅ **Official Fix**: **YES**. Patched in **Livewire v3.6.4**. Upgrade immediately to the latest version to mitigate the risk. 🛠️ Link: GitHub releases/tag/v3.6.4.
Q9What if no patch? (Workaround)
🚧 **No Patch Workaround**: If you cannot upgrade, restrict access to Livewire endpoints via WAF rules. However, given the severity (RCE), **upgrading is the only reliable mitigation**. 🚫
Q10Is it urgent? (Priority Suggestion)
🚨 **Urgency**: **CRITICAL (Priority 1)**. CVSS Score is **9.2** (High). With public exploits and RCE impact, patch immediately to prevent server takeover. ⏳
