`shell_unquoted_expansion`

Shell Unquoted Expansion — a PullGuard finding type. Findings of this type appear in the PR comment, Step Summary, SARIF (GitHub Security tab / IDE viewers), and the HTML report, each with severity, location, and the remediation guidance below.

How to fix

Double-quote the expansion — an unquoted $VAR is word-split and glob-expanded trivial effort

cp "$SRC" "$DEST"   # not: cp $SRC $DEST
cmd "${ARGS[@]}"      # arrays keep their element boundaries

Run shellcheck in CI to catch the whole class (SC2086) low effort

shellcheck path/to/script.sh

Triage

Suppress a confirmed non-issue with a committed .pullguardignore entry (pullguard ignore locally, or comment /pullguard ignore <fingerprint> <reason> on the PR — the fingerprint is printed in the PR comment’s Triage section). Entries support expiresAt for time-boxed snoozes.

Security findings at major or critical severity — and any critical finding — always surface: .pullguardignore cannot hide them. The reviewed paths that keep them visible are acknowledged (reviewed, stays in reports) and, for a confirmed false positive, a reasoned false_positive entry — visible and audited, excluded only from the merge block.
