⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Template injection vulnerability from user-controlled input.

Direct interpolation of ${{ inputs.llvm_version }} into the shell script enables code injection if a malicious value is provided. While the attack surface is limited to users with workflow dispatch permissions, defense-in-depth recommends using the env context instead.

🔒 Recommended fix: pass input via env context 
       - name: Clone llvm-project
         shell: bash
+        env:
+          LLVM_VERSION: ${{ inputs.llvm_version }}
         run: |
-          VERSION="${{ inputs.llvm_version }}"
+          VERSION="${LLVM_VERSION}"
           echo "Cloning LLVM ${VERSION}..."
           git clone --branch "llvmorg-${VERSION}" --depth 1 https://github.com/llvm/llvm-project.git .llvm

[error] 148-148: code injection via template expansion (template-injection): may expand into attacker-controllable code

(template-injection)

🤖 Prompt for AI Agents 
Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

In @.github/workflows/build-llvm.yml around lines 145 - 150, The workflow step
"Clone llvm-project" currently interpolates the user input directly into the run
script via `${{ inputs.llvm_version }}`, which allows template injection;
instead pass the input through the step's env context (set an env key like
VERSION: ${{ inputs.llvm_version }}) and then reference the safe shell variable
(`$VERSION`) inside the run script used by that step (keep the step name "Clone
llvm-project" and the shell variable `VERSION` so you can find it). Ensure the
run script uses the env variable (quoted) when printing and when supplying the
git --branch argument to avoid direct template interpolation.
