🚨 **Essence**: Gogs Git Hooks allow **OS Command Injection**. <br>💥 **Consequences**: Remote Code Execution (RCE) & Privilege Escalation. Attackers can run arbitrary commands on the server.

🛡️ **Root Cause**: Flaw in **Git Hooks** functionality. <br>⚠️ **CWE**: Not explicitly listed, but implies **Command Injection**. The UI doesn't warn users of unsafe actions.

📦 **Affected**: Gogs versions **0.5.5** through **0.12.2**. <br>🔧 **Component**: Git Hooks feature.

💀 **Attacker Actions**: Execute **Remote Code** as the Gogs user. <br>🔓 **Privileges**: Can escalate privileges if non-admin users have hook access.

🔑 **Threshold**: **High** (Requires Auth). <br>👤 **Requirement**: Must be an **authenticated** user. Not fully open to the public internet.

📜 **Exploit Status**: **Yes**, public PoC exists. <br>🔗 Links: PacketStorm & FZI research. Nuclei templates available.

🔍 **Self-Check**: Scan for Gogs versions **0.5.5-0.12.2**. <br>🧪 Test: Check if **Git Hooks** feature is enabled and accessible to non-admins.

🩹 **Fix**: Upgrade Gogs to a version **> 0.12.2**. <br>✅ Official patch addresses the hook injection flaw.

🚧 **No Patch?**: Disable **Git Hooks** feature entirely. <br>🚫 Restrict hook access to **Admins only**. Remove non-admin privileges.

🔥 **Urgency**: **High**. <br>⚡ RCE is critical. Even with auth requirement, lateral movement is easy. Patch immediately!
