Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Qwik < 1.19.0 suffers from **Prototype Pollution** in `formToObj`. ๐ **Consequences**: Attackers can tamper with `Object.prototype`, leading to **Privilege Escalation**, **Auth Bypass**, or **DoS**.โฆ
๐ก๏ธ **Root Cause**: **CWE-1321** (Prototype Pollution). The `formToObj` function fails to sanitize input, allowing malicious keys to pollute the global object prototype. ๐ Flawed input validation.
Q3Who is affected? (Versions/Components)
๐ฅ **Affected**: **Qwik** framework versions **prior to 1.19.0**. ๐ฆ Vendor: **QwikDev**. If you use older Qwik builds, you are at risk! โ ๏ธ
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: Unauthenticated actors can **pollute Object.prototype**. This enables **Auth Bypass** (login without creds), **Privilege Escalation** (admin access), or **DoS** (crash app). ๐ต๏ธโโ๏ธ
Q5Is exploitation threshold high? (Auth/Config)
๐ **Exploitation Threshold**: **LOW**. CVSS: **AV:N** (Network), **AC:L** (Low Complexity), **PR:N** (No Privileges), **UI:N** (No User Interaction). Zero-touch exploitation possible! ๐ฏ
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exploit**: **No PoC** currently listed in data. ๐ซ However, the vulnerability is well-understood (Prototype Pollution). Wild exploitation is likely imminent given the low barrier. ๐ฐ๏ธ
Q7How to self-check? (Features/Scanning)
๐ **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. ๐งช
Q8Is it fixed officially? (Patch/Mitigation)
โ **Official Fix**: **YES**. Patched in **Qwik 1.19.0+**.โฆ
๐ง **No Patch Workaround**: **Upgrade immediately**. If impossible, **sanitize all inputs** passed to `formToObj`. Validate keys to prevent `__proto__` or `constructor` injection. ๐
Q10Is it urgent? (Priority Suggestion)
๐ฅ **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! โณ
