Q: How to self-check? (Features/Scanning)

🔍 **Self-Check**: 1. Check Bruno version (< 3.2.1). 2. Scan `node_modules` for modified `axios` checksums. 3. Monitor for suspicious outbound network connections from Bruno.

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

✅ **Fixed?**: **Yes**. 🔧 **Patch**: Upgrade to **Bruno 3.2.1** or later. 📝 **Advisory**: See GHSA-658g-p7jg-wx5g.

Q: What if no patch? (Workaround)

🚧 **No Patch?**: 1. **Uninstall** Bruno immediately. 2. **Clear** npm cache (`npm cache clean --force`). 3. **Reinstall** from verified sources. 4. **Scan** system for RAT artifacts.

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **CRITICAL**. ⏱️ **Priority**: **Immediate Action Required**. ⚠️ **Reason**: Active supply chain compromise with full system access. Do not delay.

Question 1

What is this vulnerability? (Essence + Consequences)

Accepted Answer

🚨 **Essence**: A supply chain attack via a compromised `axios` npm package.
💥 **Consequences**: Bruno IDE installs a cross-platform Remote Access Trojan (RAT). Your machine is compromised.

Question 2

Root Cause? (CWE/Flaw)

Accepted Answer

🛡️ **Root Cause**: **CWE-494** (Download of Code Without Integrity Check).
🔍 **Flaw**: The dependency `axios` was hijacked by attackers, injecting malicious code into legitimate updates.

Question 3

Who is affected? (Versions/Components)

Accepted Answer

👥 **Affected**: Users of **Bruno** (API IDE).
📦 **Version**: Versions **before 3.2.1**.
🏢 **Vendor**: usebruno.

Question 4

What can hackers do? (Privileges/Data)

Accepted Answer

🕵️ **Hacker Actions**: Full Remote Access.
🔓 **Privileges**: High (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
📂 **Data**: Complete system control, data theft, and lateral movement.

Question 5

Is exploitation threshold high? (Auth/Config)

Accepted Answer

⚡ **Threshold**: **LOW**.
🔑 **Auth**: None required (PR:N).
🖱️ **UI**: None required (UI:N).
🌐 **Network**: Network accessible (AV:N). Just installing the vulnerable version triggers it.

Question 6

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

Accepted Answer

📢 **Public Exp?**: **Yes**.
🔗 **Proof**: The malicious package is already live on npm.
🚫 **PoC**: No specific script needed; the compromised package *is* the exploit.

Question 7

How to self-check? (Features/Scanning)

Accepted Answer

🔍 **Self-Check**:
1. Check Bruno version (< 3.2.1).
2. Scan `node_modules` for modified `axios` checksums.
3. Monitor for suspicious outbound network connections from Bruno.

Question 8

Is it fixed officially? (Patch/Mitigation)

Accepted Answer

✅ **Fixed?**: **Yes**.

What if no patch? (Workaround)

Accepted Answer

🚧 **No Patch?**:
1. **Uninstall** Bruno immediately.
2. **Clear** npm cache (`npm cache clean --force`).
3. **Reinstall** from verified sources.
4. **Scan** system for RAT artifacts.

Question 10

Is it urgent? (Priority Suggestion)

Accepted Answer

🔥 **Urgency**: **CRITICAL**.
⏱️ **Priority**: **Immediate Action Required**.
