CVE-2026-40903 — AI Deep Analysis Summary

🚨 **Essence**: goshs < 2.0.0-beta.6 suffers from an **ArtiPACKED** flaw. 💥 **Consequences**: Critical data breach! Your **GITHUB_TOKEN** leaks via workflow artifacts. Total compromise of secrets.

🛡️ **Root Cause**: **CWE-829** (Inappropriate Control of Information Through Exclusion List). The server fails to properly sanitize or block specific artifact patterns, allowing sensitive data to slip through.

👥 **Affected**: Users running **goshs** (by Patrick Hener). Specifically versions **prior to 2.0.0-beta.6**. If you are on beta.6 or later, you are safe! ✅

💀 **Hacker Power**: Full access to **GITHUB_TOKEN**. This means they can read/write repos, deploy malicious code, and escalate privileges. High impact on Confidentiality & Integrity. 📉

⚡ **Threshold**: **LOW**. CVSS shows **AV:N** (Network), **AC:L** (Low Complexity), **PR:N** (No Privs needed). Hackers just need network access to the server. No UI interaction required. 🎯

🔍 **Public Exp?**: No specific PoC code provided in the data. However, the vulnerability is well-defined (ArtiPACKED). Wild exploitation is likely given the low barrier to entry. ⚠️

🔎 **Self-Check**: Scan your infrastructure for **goshs** instances. Check version numbers! If < 2.0.0-beta.6, you are vulnerable. Look for unusual artifacts in GitHub workflows containing tokens. 🕵️‍♂️

🩹 **Official Fix**: **YES**. Upgrade to **goshs 2.0.0-beta.6** or later. The vendor (Patrick Hener) has issued a security advisory (GHSA-hpxj-9fgp-fhhf). 📄

🚧 **No Patch?**: Isolate the goshs server from the internet. Restrict access to trusted IPs only. Monitor GitHub workflow logs for leaked tokens immediately. Rotate any exposed GITHUB_TOKENs! 🔄

🔥 **Urgency**: **CRITICAL**. CVSS Score implies High Impact (C:H, I:H). Token leakage is a nightmare. Patch **IMMEDIATELY**. Do not wait! 🏃‍♂️💨
