Q: Root Cause? (CWE/Flaw)

🛡️ **Root Cause**: **CWE-20** (Improper Input Validation). The framework fails to properly sanitize or escape user-supplied input before rendering it in HTML templates, allowing script injection.

Q: Who is affected? (Versions/Components)

📦 **Affected**: **gofiber/template** versions **prior to 3.1.9**. Any project using this Go-based web framework component with these older versions is at risk. 📉 **Status**: Outdated versions only.

Q: What can hackers do? (Privileges/Data)

💻 **Attacker Actions**: Execute arbitrary JavaScript in the victim's browser. 🎯 **Impact**: Steal session cookies, hijack user accounts, deface pages, or redirect users to malicious sites. High Integrity (I:H) impact.

Q: Is it fixed officially? (Patch/Mitigation)

✅ **Fixed**: **Yes**. Official patch released in **version 3.1.9**. 📝 **Reference**: GitHub commit `28cff3ac` and GHSA advisory `GHSA-4mq2-gc4j-cmw6`. Update immediately to resolve. 🛠️

Q: Is it urgent? (Priority Suggestion)

⚡ **Urgency**: **HIGH**. CVSS Score indicates **High Integrity** impact with **Low** exploitation difficulty. Even without public PoCs, the risk is significant for any public-facing app. Patch ASAP! 🏃♂️💨
