Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Arbitrary File Upload via missing validation. π₯ **Consequences**: Full system compromise, data theft, or server takeover due to CWE-434.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-434** (Unrestricted Upload of File with Dangerous Type). The plugin fails to verify file extensions/types before processing uploads.
