CVE-2026-25150 — AI Deep Analysis Summary

🚨 **Essence**: Qwik < 1.19.0 suffers from **Prototype Pollution** in `formToObj`. 📉 **Consequences**: Attackers can tamper with `Object.prototype`, leading to **Privilege Escalation**, **Auth Bypass**, or **DoS**.…

🛡️ **Root Cause**: **CWE-1321** (Prototype Pollution). The `formToObj` function fails to sanitize input, allowing malicious keys to pollute the global object prototype. 🐛 Flawed input validation.

👥 **Affected**: **Qwik** framework versions **prior to 1.19.0**. 📦 Vendor: **QwikDev**. If you use older Qwik builds, you are at risk! ⚠️

💀 **Attacker Capabilities**: Unauthenticated actors can **pollute Object.prototype**. This enables **Auth Bypass** (login without creds), **Privilege Escalation** (admin access), or **DoS** (crash app). 🕵️‍♂️

🔓 **Exploitation Threshold**: **LOW**. CVSS: **AV:N** (Network), **AC:L** (Low Complexity), **PR:N** (No Privileges), **UI:N** (No User Interaction). Zero-touch exploitation possible! 🎯

📜 **Public Exploit**: **No PoC** currently listed in data. 🚫 However, the vulnerability is well-understood (Prototype Pollution). Wild exploitation is likely imminent given the low barrier. 🕰️

🔍 **Self-Check**: Scan for Qwik versions **< 1.19.0**. Check if `formToObj` is used with unsanitized user input. Use SAST tools to detect prototype pollution patterns in JS code. 🧪

✅ **Official Fix**: **YES**. Patched in **Qwik 1.19.0+**.…

🚧 **No Patch Workaround**: **Upgrade immediately**. If impossible, **sanitize all inputs** passed to `formToObj`. Validate keys to prevent `__proto__` or `constructor` injection. 🛑

🔥 **Urgency**: **HIGH**. CVSS Score implies **High Integrity** impact with **Low** effort. Patch to **v1.19.0+** ASAP to prevent Auth Bypass and DoS. Don't wait! ⏳
