CVE-2026-37531 — AI Deep Analysis Summary

🚨 **Essence**: A critical **Zip Slip** (Path Traversal) combined with a **TOCTOU** race condition in AGL's widget installation.…

🛡️ **Root Cause**: 1. **CWE-22**: `is_valid_filename` only blocks absolute paths, ignoring `../` sequences. 🚫 2. **CWE-367**: `zread` resolves relative paths against `workdirfd`, allowing escape. ⚡ 3.…

📦 **Affected**: AGL (Automotive Grade Linux) `app-framework-main`. 🚗 🔢 **Version**: **17.1.12 and earlier**. ⚠️ 🔧 **Component**: `wgtpkg-zip.c` and `wgtpkg-install.c`.

🕵️ **Attacker Actions**: - Write arbitrary files to **any directory** outside the sandbox. 📝 - **Bypass** signature validation (malicious files persist even if signatures fail).…

🔓 **Threshold**: **LOW**. 📉 - **Auth**: None required (`PR:N`). 🔑 - **UI**: None required (`UI:N`). 👀 - **Network**: Remote (`AV:N`). 🌐 - **Complexity**: Low (`AC:L`).…

📜 **Public Exp**: **No** specific PoC/Wild Exp listed in data. 🚫 🔗 **Refs**: Gist and Gerrit links provided, but no active exploit code confirmed.…

🔍 **Self-Check**: 1. Scan for `app-framework-main` version **≤ 17.1.12**. 📊 2. Check if `wgtpkg-zip.c` lacks `../` validation. 🧐 3. Verify if widget extraction precedes signature checks. ⏳ 4.…

🩹 **Fix**: **Yes**, implied by the CVE publication. 📅 📅 **Published**: 2026-05-01. 🗓️ 🔧 **Mitigation**: Update to a version **after 17.1.12**. ✅ 🛡️ **Official Patch**: Available via AGL Gerrit/Updates. 🔄

🚧 **No Patch Workaround**: 1. **Disable** automatic widget installation. 🚫 2. **Manually verify** signatures **before** extraction. ⚖️ 3. **Restrict** file system permissions for the installation process. 🔒 4.…

🔥 **Urgency**: **CRITICAL**. 🚨 📈 **Priority**: **P1** (Immediate Action). 📉 **CVSS**: 9.8 (High). ⚡ **Reason**: Remote, unauthenticated, full system compromise. Do not wait! 🏃‍♂️💨
