fix: redact non-SQL content echoed in safety threat messages (main sanity failure)#1111anandgupta42 wants to merge 5 commits into
Conversation
The main-only Sanity (Verdaccio) security test 6/15 (`altimate check ../../../../etc/passwd` must not reflect file contents) fails since #1090: surfacing real `ThreatFinding` messages exposed that the engine's `multi_statement` rule quotes the raw "statement type" token verbatim — for non-SQL input that is the file's content (`Disallowed statement type: ROOT:X:0:0:…`), an information-disclosure echo. The sanity job is skipped on PRs, so #1090's CI could not catch it. Fix at the dispatcher boundary (covers CLI, tools, and review): - `EngineCoerce.redactThreatText`: keeps SQL-keyword-like statement types (`DROP`, `ALTER TABLE`) and replaces arbitrary content with `<non-SQL content redacted>` in threat message/detail. - `multi_statement` threats also redact `matched_pattern` — for that rule the pattern IS the raw input line. Injection rules keep their SQL-shaped patterns. Diff-scoping keys stay consistent (base and head redact identically). - Applied in the `altimate_core.safety` handler and the composite check. Tests: unit coverage for the redaction (keyword kept / content redacted / unrelated messages untouched) plus real-engine tests proving passwd-like input no longer echoes through either handler while `DROP` survives in messages. Verified the exact sanity scenario locally: CLI output now shows `<non-SQL content redacted>`. Filed upstream for the engine-side echo: to be linked.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change redacts sensitive safety output across command-line, analysis, and grading paths. A bounded merge-readiness risk remains because the SQL analysis and grading coverage may not prove that redaction is applied to real safety results in those paths; this should receive explicit owner follow-up, but no blocking defect is established.

Cursor review catch: redacting the head scan BEFORE the base subtraction rewrote `multi_statement` matched_patterns to "<redacted>", so base keys (raw) never matched and pre-existing threats resurfaced as newly introduced. Redaction now runs after diff-scoping — subtraction compares raw engine patterns on both sides. Regression test: identical base/head passwd-like input yields zero threats and safe:true.

Round-2 review hardening on the redaction:
- Keyword ALLOWLIST, not shape: the token is kept only when its first word
is a known SQL statement keyword — shape alone passed content like
"TOP SECRET PASSWORD" or "AKIAIOSFODNN7EXAMPLE".
- Greedy quoted match: an embedded apostrophe in the raw token
("Statement type 'DROP'ROOT:X:0' is not…") previously closed the match
early and leaked the remainder; greedy capture spans to the last quote
and embedded quotes fail the check, redacting everything inside.
- All scanSql consumers covered: `redactScan` moved to `EngineCoerce`
(pure, no NAPI import) and applied in `sql.analyze` (copied raw
message/detail into issues) and the `altimate_core.grade` handler
(EvalResult embeds a full safety scan that the CLI grade check renders).
- Tests: allowlist/apostrophe cases; composite + safety tests assert
success AND non-empty threats AND the redaction marker (previously
vacuous if threats were missing); sql.analyze + grade echo tests;
Dispatcher.reset() and telemetry-env restore in afterAll; shared
dispatcher import hoisted into beforeAll.

- `isSqlStatementType` now requires EVERY word of the preserved phrase to
come from the SQL keyword vocabulary (statement keywords first, auxiliary
words like TABLE/INDEX/IF/EXISTS after) — checking only the first word
preserved attacker tails such as "SET SECRET PASSWORD" verbatim. Since
preserved text is a subset of the fixed vocabulary, no attacker-specific
content can survive. Tests cover keyword-prefixed tails and compound
types ("DROP INDEX IF EXISTS" stays useful).
- `sql.analyze` test asserts non-empty safety issues + the redaction marker
(was vacuous if the scan produced nothing).
- Grade test corrected to the REAL EvalResult shape: its `safety` section is
`{ method, score }` — there are no nested threats to echo (the handler
redaction stays as defense-in-depth). The test now asserts the whole
result is echo-free minus the by-contract input-echo fields (`sql`,
`lint.sql`), which the CLI never renders.

Two review comments pulled opposite directions — cubic wanted compound types
like "DELETE FROM" preserved; Codex wanted exact statement types instead of
any keyword-vocabulary ordering ("SELECT DELETE UPDATE" leaked verbatim).
Live-probing the 0.7.0 engine across DDL/DML/DCL/TCL settles both: the
engine emits SINGLE-WORD statement types only ({ALTER, BEGIN, CALL, CREATE,
DELETE, DROP, EXPLAIN, GRANT, INSERT, SET, TRUNCATE, UPDATE}). The allowlist
is now an exact single-keyword match — the strictest rule that never redacts
anything the engine actually produces: multi-word input can only be
non-engine content, so keyword-prefixed tails and keyword permutations both
redact. Vocabulary-ordering and multi-word tests updated with the probe
rationale inline.

SUGGESTION: Doc comment still describes the superseded keyword-prefix rule
isSqlStatementType now keeps a token only when it is exactly one allowlisted statement keyword, but this docstring still says a token is kept when it "starts with a known SQL statement keyword" and calls it a "keyword phrase" — implying ALTER TABLE or SET FOO survive redaction. Update the wording to the exact single-keyword contract so future readers don't rely on the weaker rule the last two commits removed.

SUGGESTION: Shape regex is looser than the exact-keyword rule needs
With exact single-keyword matching, the _, $, space, and {0,31} length allowance are all dead: any token containing them can never be a member of SQL_STATEMENT_KEYWORDS. Only the ASCII restriction is still load-bearing and must stay (e.g. "ſELECT".toUpperCase() === "SELECT", so a Unicode lookalike would otherwise slip through the allowlist).

SUGGESTION: Stale comment describes the removed first-word rule
The rule is no longer "the first word must be a SQL statement keyword" — isSqlStatementType now requires the token to be exactly one allowlisted keyword, so even SET FOO redacts. Reword to match the exact-match rule.

Fixes the

The engine'smulti_statementrule quotes the raw "statement type" token verbatim, and itsmatched_patternis the raw input line — for non-SQL input (altimate check ../../../../etc/passwd) that reflects the file's contents into CLI output (Disallowed statement type: ROOT:X:0:0:…), which the sanity test rightly flags as an information-disclosure hazard.Fix at the dispatcher boundary so every consumer (CLI, tools, review) is covered:
EngineCoerce.redactThreatTextkeeps SQL-keyword-like statement types (DROP,ALTER TABLE) and replaces arbitrary content with<non-SQL content redacted>in threatmessage/detail.multi_statementthreats additionally redactmatched_pattern(for that rule the pattern IS the raw input line); injection rules keep their SQL-shaped patterns.
