CVSS 10.0 ยท Critical

Q1What is this vulnerability? (Essence + Consequences)

๐Ÿšจ **Essence**: A critical flaw in Coolify allows low-privilege users to access root user SSH private keys. ๐Ÿ“‰ **Consequences**: Complete system compromise.โ€ฆ

Q2Root Cause? (CWE/Flaw)

๐Ÿ›ก๏ธ **CWE**: CWE-522 (Insufficiently Protected Credentials). ๐Ÿ” **Flaw**: The application fails to restrict access to sensitive cryptographic material.โ€ฆ

Q3Who is affected? (Versions/Components)

๐Ÿ“ฆ **Vendor**: coollabsio. ๐Ÿ“ฆ **Product**: Coolify (Open-source Heroku/Netlify/Vercel alternative). ๐Ÿ“… **Affected Versions**: v4.0.0-beta.434 and all earlier versions. ๐Ÿšซ Newer versions are likely safe. โœ…

Q4What can hackers do? (Privileges/Data)

๐Ÿ”‘ **Privileges**: Escalates from Low-Privilege to **Root**. ๐Ÿ“‚ **Data**: Exposes Root User SSH Private Keys.โ€ฆ

Q5Is exploitation threshold high? (Auth/Config)

๐Ÿ”“ **Auth Required**: Yes, but **Low** privilege. ๐Ÿ“‰ **Threshold**: Low. An attacker only needs basic access to the Coolify interface. ๐Ÿšถ **Config**: No complex configuration needed. Just valid low-level credentials. โšก

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

๐Ÿ“œ **Public Exp**: No specific PoC code provided in the data. ๐ŸŒ **Status**: Advisory published (GHSA-qwxj-qch7-whpc). ๐Ÿ•ต๏ธ **Risk**: High likelihood of wild exploitation due to simplicity (just reading a file/key). โš ๏ธ

Q7How to self-check? (Features/Scanning)

๐Ÿ” **Check**: Verify your Coolify version. ๐Ÿ“‹ **Scan**: Look for unauthorized access to SSH key storage endpoints. ๐Ÿ›ก๏ธ **Audit**: Check if low-privilege users can retrieve root credentials via API or UI. ๐Ÿšจ

Q8Is it fixed officially? (Patch/Mitigation)

๐Ÿ”ง **Fix**: Upgrade to a version **newer than** v4.0.0-beta.434. ๐Ÿ“ข **Source**: Official GitHub Security Advisory (GHSA-qwxj-qch7-whpc). โœ… **Action**: Immediate update recommended by vendor. ๐Ÿ”„

Q9What if no patch? (Workaround)

๐Ÿšง **Workaround**: Restrict low-privilege user permissions strictly. ๐Ÿ”’ **Mitigation**: Disable SSH key exposure in UI/API if possible. ๐Ÿ›‘ **Isolate**: Segregate critical root keys from the application layer. ๐Ÿงฑ

Q10Is it urgent? (Priority Suggestion)

๐Ÿ”ฅ **Priority**: **CRITICAL**. ๐Ÿšจ **Urgency**: Immediate action required. CVSS Score indicates High impact (C:H, I:H, A:H). ๐Ÿ“‰ **Risk**: Root compromise is game-over for most servers. ๐Ÿƒโ€โ™‚๏ธ
