CVSS 9.9 Β· Critical

Q1What is this vulnerability? (Essence + Consequences)

🚨 **Essence**: Budibase has an **Unsafe `eval()`** flaw in view filtering. <br>πŸ’₯ **Consequences**: Allows **Arbitrary JavaScript Execution** on the server.…

Q2Root Cause? (CWE/Flaw)

πŸ›‘οΈ **Root Cause**: **CWE-20** (Improper Input Validation). <br>πŸ” **Flaw**: The view filter implementation blindly uses `eval()`, failing to sanitize user input before execution.

Q3Who is affected? (Versions/Components)

πŸ“¦ **Affected**: **Budibase** (Low-code platform). <br>πŸ“‰ **Versions**: **< 3.30.4**. <br>🏒 **Vendor**: Budibase (UK-based open-source project).

Q4What can hackers do? (Privileges/Data)

πŸ•΅οΈ **Attacker Actions**: Execute **Arbitrary JS** on the server. <br>πŸ”‘ **Impact**: Steal **Environment Variables**, API Keys, and **Credentials**. Full system compromise potential.

Q5Is exploitation threshold high? (Auth/Config)

πŸ” **Threshold**: **Medium**. <br>βœ… **Auth Required**: Yes, needs **Authenticated User** access. <br>βš™οΈ **Config**: Low complexity (AC:L), no UI interaction needed (UI:N).

Q6Is there a public Exp? (PoC/Wild Exploitation)

πŸ“œ **Public Exp?**: **No PoC** listed in data. <br>⚠️ **Status**: References point to GitHub Advisory & PRs. Wild exploitation likely low risk currently, but **CVSS Score is High**.

Q7How to self-check? (Features/Scanning)

πŸ” **Self-Check**: Scan for **Budibase** instances. <br>πŸ“‹ **Verify Version**: Check if running **< 3.30.4**. <br>πŸ‘€ **Access**: Do you have authenticated user accounts? If yes, you are vulnerable.

Q8Is it fixed officially? (Patch/Mitigation)

βœ… **Fixed?**: **Yes**. <br>πŸ”§ **Patch**: Upgrade to **Version 3.30.4** or later. <br>πŸ”— **Source**: GitHub Release & Commit `3486598`.

Q9What if no patch? (Workaround)

🚧 **No Patch?**: **Isolate** the instance. <br>🚫 **Restrict Access**: Remove public/untrusted authenticated users. <br>πŸ”„ **Monitor**: Watch for suspicious JS execution logs in view filters.

Q10Is it urgent? (Priority Suggestion)

πŸ”₯ **Urgency**: **HIGH**. <br>πŸ“ˆ **Priority**: **Immediate Patching**. <br>βš–οΈ **Reason**: CVSS **H**igh severity (C:H, I:H). Credential leakage is catastrophic for internal apps.
