Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: SandboxJS < 0.8.29 has a critical flaw where the key used for validation doesn't match the key used for property access.β¦
π₯ **Affected**: Users running **SandboxJS** by developer **nyariv**. Specifically, versions **0.8.29 and earlier**. If you are using this security assessment tool for evaluation, you are at risk. β οΈ
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: With **CVSS 3.1 High** (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H), hackers can: 1. **Escape the sandbox** completely. 2. Access **Confidential Data** (C:H). 3. **Modify** system state (I:H). 4.β¦
π **Exploitation Threshold**: **LOW**. The vector is Network (AV:N), Attack Complexity is Low (AC:L), and no Privileges (PR:N) or User Interaction (UI:N) are required.β¦
π **Public Exploit**: Currently, the `pocs` list is empty in the data. However, the GitHub Advisory (GHSA-7x3h-rm86-3342) and source code link are public.β¦
π **Self-Check**: 1. Check your SandboxJS version. Is it < 0.8.29? 2. Review `src/executor.ts` around line 304 for the key mismatch logic. 3. Use static analysis tools to detect CWE-367 patterns in JS execution engines.β¦
π **No Patch Workaround**: If you cannot update, **disable** the vulnerable execution features or isolate the SandboxJS instance in a highly restricted network segment.β¦
π₯ **Urgency**: **CRITICAL**. With a High CVSS score, no auth required, and network accessibility, this is a **Priority 1** issue. Patch immediately to prevent potential sandbox escapes and data breaches. Do not ignore! β³
