⚡ **Threshold**: **LOW**. 🚫 **Auth**: None required (PR:N). 🖱️ **UI**: None required (UI:N). 🌍 **Network**: Remote (AV:N). 📉 **Complexity**: Low (AC:L). Any unauthenticated user can trigger this via SNS webhooks.

🔍 **Public Exploit**: **No**. The `pocs` array is empty in the data. 🚫 **Wild Exploitation**: No evidence of widespread active exploitation yet. ⚠️ **Risk**: Low barrier to write an exploit, but no public PoC available.

🔎 **Self-Check**: Scan for **Plunk versions < 0.7.0**. 🔍 **Feature**: Look for **SNS webhook** configurations. 🛠️ **Tooling**: Use SSRF scanners targeting webhook endpoints.…
