security: Command injection via unquoted variable in growth.sh line 67

Line: 67
Severity: HIGH

Description: Unquoted variable interpolation in bun command at line 67:

POST_COUNT=$(bun -e "const d=JSON.parse(await Bun.file('${REDDIT_DATA_FILE}').text()); console.log(d.postsScanned ?? d.posts?.length ?? 0)")

The REDDIT_DATA_FILE variable is interpolated into a bun command without proper quoting. If an attacker can control the temp file path (e.g., through symlink attacks or race conditions), they could inject malicious JavaScript code.

Recommendation:

• Use environment variable passing instead of string interpolation:

_DATA_FILE="${REDDIT_DATA_FILE}" bun -e "const d=JSON.parse(await Bun.file(process.env._DATA_FILE).text()); console.log(d.postsScanned ?? d.posts?.length ?? 0)"

Triage Assessment

Status: Requires manual security review in growth.sh

This issue documents a legitimate command injection risk via unquoted variable interpolation in bun command. The file is off-limits for automated refactoring per CLAUDE.md rules. Recommend prioritizing this fix alongside other growth.sh security concerns.

Labels: Confirm as security-review-required (appropriate) + no status label needed (manual review case).
