* fix(careful): mask git commit -m content to prevent MEDIUM-tier false positives (#1060) MEDIUM-tier checks matched the full command string including quoted -m text. A commit like 'git commit -m fix: prevent drop table in migration' triggered the SQL DROP warning even though no SQL was being executed. Build CMD_MEDIUM by stripping -m quoted content from git commit commands before MEDIUM checks. Real destructive commands outside the quoted string still match, so true positives are unaffected. Add tests: commit message patterns do not warn; chained real DROP/TRUNCATE still warns. * fix(careful): replace sed masking with quote-aware awk scanner (#1060) The sed-based -m content masker had two bypass paths that capy-ai identified: 1. Single-quoted message containing a double-quote boundary: git commit -m 'note -m "' && rm -rf build && echo '"' The double-quote pass matched '-m "' inside the single-quoted string, swallowing '&& rm -rf build && echo '; the rm vanished from CMD_MEDIUM. 2. Double-quoted message with a command substitution: git commit -m "$(rm -rf build)" sed replaced the content including the $(...), so the substitution — which executes in the shell — was masked away. Replace the sed substitution with a quote-aware awk scanner that: - Walks the command string tracking single-quote, double-quote, and backslash state, so it only treats a delimiter as a message boundary when the shell would. - Masks single-quoted messages (always literal) and double-quoted messages that contain no $, backtick, or backslash (safe to mask — no expansion). - Leaves double-quoted messages with $, backtick, or backslash unmasked so command substitutions stay visible to the MEDIUM checks. - Handles -m, -am, --message, and --message= forms. Four new tests added as requested (alongside the original six): - single-quoted message with embedded double-quote + chained rm → warns - commit message with $(rm -rf build) → warns - git push --force chained after commit → warns - git commit -am "drop table notes" → silent (message masked) * fix(careful): read the commit-message masker from a file, so bash 3.2 can parse the hook (#1060) Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com> * fix(careful): scan the command as one string, so a newline still separates commands from the message (#1060) Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com> * fix(careful): mask only git commit's own message; a piped commit or another command's -m stays visible (#1060) Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com> * fix(careful): mask a quoted-delimiter heredoc message; any other substitution or heredoc leaves the command unmasked (#1060) Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com> * fix(careful): a pipe, process substitution or parameter expansion after the message unmasks it; redirections and comments parse like bash (#1060) Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com> * docs(changelog): careful masks git commit's own message (#1060, port of #3221) Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com> --------- Co-authored-by: Bhumika-1432006 <guravbhumika808@gmail.com> Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>
