Session-export fields may contain user-controlled or model-produced text. The protected exporter applied ordinary CSV quoting but did not distinguish spreadsheet formula markers. The repair routes every exported field through a package-owned
csvFieldboundary that prefixes an apostrophe when the first non-whitespace character is=,+,-, or@, then applies the existing quote/comma/CR/LF escaping contract.The security boundary is isolated in
src/lib/csv.tsrather than left private inside the Next.js route so it can be exercised without mocking authentication, Prisma, or route lifecycle.csv.test.tscovers direct and whitespace-prefixed formula markers plus ordinary CSV quoting/null behavior. The route imports that tested function; it does not duplicate the sanitizer.This PR does not claim arbitrary-code execution in every spreadsheet client or blanket protection for every spreadsheet/import product. The accepted claim is narrower: exported attacker-controlled cells that match the governed formula-admission markers are emitted as text-prefixed CSV cells before ordinary CSV escaping.
Intervening-delta repair
The generated branch had three unrelated security-governance changes: it replaced the repository-wide
.jules/sentinel.md, added a new.trivyignorewith three CVE suppressions, and appended the same CVEs toosv-scanner.tomlwithout establishing a dependency/root-fix decision in this CSV lane. Those changes were not required to fix CSV cell emission and weakened evidence separation.Normal descendants restored
.jules/sentinel.mdandosv-scanner.tomlbyte-for-byte to protected authority and deleted the branch-only.trivyignore. No scanner waiver or unrelated dependency exception remains in the effective diff.Exact-head acceptance
Fresh workflows have materialized for
34b71467...: CI33997791615, Security Scan33997791476, SAST Semgrep33997791441, and CodeQL PR33997791428; all are currently queued/non-terminal. Predecessor results are not transferred.Keep Draft until one unchanged exact head has terminal applicable test/lint/typecheck/security/SAST/CodeQL evidence, zero valid unresolved findings, fresh protected-base compatibility, and the then-live independent-review requirement. Do not self-approve, add a source-neutral retrigger, restore scanner suppressions, force-push/destructively rebase, or weaken gates.
