โ๏ธ **Threshold**: Medium-High for Local Attack. ๐ **Auth**: Requires **Local User Access** (no remote exploit). ๐ **Config**: Attacker must have write permissions to `%PROGRAMDATA%\DockerDesktop\version-bin`.โฆ
๐ข **Public Exploit**: Yes. ๐ **References**: PacketStorm Security (File ID: 157404) and Medium articles detail the EoP technique. ๐ **Wild Exploitation**: Likely limited to local attackers with access.โฆ
โ **Fixed**: Yes. ๐ฆ **Patch**: Upgrade Docker Desktop Community Edition to **version 2.1.0.1 or later**. ๐ **Mitigation**: The vendor addressed the file verification logic in the update.โฆ
๐ฅ **Urgency**: HIGH for Windows Docker Users. ๐ **Priority**: P1/P2. โ ๏ธ **Reason**: Easy local exploitation by any local user. ๐ข **Impact**: Compromises container security and host credentials.โฆ
