Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Plane v0.23.0- has a wildcard image retrieval flaw.โฆ
๐ก๏ธ **Root Cause**: **CWE-918** (SSRF). The app uses **wildcard support** for image hosts. ๐ **Flaw**: It fails to validate the source domain, allowing requests to internal or malicious URLs.
Q3Who is affected? (Versions/Components)
๐ฅ **Affected**: **Plane** (Open-source project planning tool). ๐ฆ **Versions**: **v0.23.0 and earlier**. ๐ข **Vendor**: makeplane. Self-hosted instances are at risk.
Q4What can hackers do? (Privileges/Data)
๐ **Hackers' Power**: Can induce **Server-Side Execution** of requests. ๐ **Data Impact**: High Availability impact (CVSS A:H), Low Integrity (I:L).โฆ
๐งช **Public Exp?**: No specific PoC code listed in data. ๐ **Status**: Advisory confirmed (GHSA-39gx-38xf-c348). Wild exploitation is likely possible due to low complexity.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for Plane instances < v0.23.0. ๐ผ๏ธ **Feature**: Check if image URLs allow wildcard domains. ๐ ๏ธ **Tool**: Use SSRF scanners to test image endpoints against internal IPs.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed?**: **YES**. ๐ **Published**: 2024-10-11. ๐ **Patch**: See GitHub Advisory & Commit b9f78ba. Upgrade to the latest version immediately.
Q9What if no patch? (Workaround)
๐ง **No Patch?**: Implement strict **URL allowlisting** for image hosts. ๐ซ **Block**: Wildcards and internal IP ranges. ๐ก๏ธ **WAF**: Filter outbound requests from the Plane server.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **HIGH**. ๐จ **Priority**: Critical. Remote, unauthenticated, low complexity. Patch immediately to prevent SSRF attacks and data exposure.
