Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Command Injection: Using direct GitHub template expressions like `${{ github.ref }}` in inline run scripts allows untrusted branch names to inject malicious shell commands, potentially compromising the CI runner and repository secrets.
Memory Injury: Bypassing safety checks using `Bytes.unsafe_set` in core string helper functions can lead to out-of-bounds writes (buffer overflows) if loop boundaries are incorrect, causing instability or memory corruption in the compiler toolchain.
