The audit flags one legacy SQL text construction and one dynamic wildcard regex in mail policy validation. The SQL table name is allowlisted, and wildcard patterns are escaped, but both should be made explicit and tested.

Classification: review / hardening.

Report evidence:

  • govoplan-mail/src/govoplan_mail/backend/mail_profiles.py:292 uses text(f"...") with an allowlisted table name.
  • govoplan-mail/webui/src/features/mail/mailPolicyValidation.ts:94 builds a regex from a policy pattern.
  • Bandit: B608; Semgrep: avoid-sqlalchemy-text, detect-non-literal-regexp.

Suggested next steps:

  • Move legacy subject table lookup behind a small allowlisted SQL helper or separate explicit queries.
  • Add tests for rejected table names and wildcard edge cases.
  • Consider bounded wildcard matching without dynamic RegExp if the UI can accept arbitrary long patterns.

Codex State: done

Summary

  • Removed dynamic table-name SQL in legacy mail policy subject lookup by splitting user/group queries into fixed SQL statements.
  • Replaced frontend wildcard matching via dynamic RegExp with an iterative wildcard matcher.

Changed Files

  • src/govoplan_mail/backend/mail_profiles.py
  • webui/src/features/mail/mailPolicyValidation.ts

Verification

  • python3 -m py_compile src/govoplan_mail/backend/mail_profiles.py
  • PATH=/mnt/DATA/git/govoplan-core/webui/node_modules/.bin:... npm run test:mail-ui

Local fix is ready to push.
