🟡 404 handler registered after error handler, making it unreachable for Express error routing
The 404 handler at line 231 is registered after the global error handler at line 221. In Express, a 4-argument middleware (err, req, res, next) is an error handler, but the subsequent 2-argument middleware at line 231 is a regular handler. While Express does distinguish these correctly (error handlers only fire for errors, regular handlers for non-error requests), the ordering means that if a route calls next(err), the error handler at line 221 catches it. However, if the error handler itself calls next() (which it doesn't here, but is a concern), the 404 handler would never see that. The more concrete issue: because res.status(status).json(...) at line 224 doesn't call next(), Express never proceeds to the 404 handler for error cases. But for actual 404s (no route matched), Express correctly falls through all middleware. So this ordering is actually correct for Express. However, the 404 handler will never be reached for any request that matches one of the defined routes, since matched routes handle responses. This is actually a non-issue.

🔴 SSN validation in identity check passes encrypted SSN values to regex, always failing
In identityService.js:56, the validateSSN function is called with borrower.ssn_last_four directly from the database. Since SSN is stored encrypted (AES-256-GCM with enc: prefix, per los-app/backend/src/routes/applications.js:40), the value will be an encrypted string like enc:base64iv:base64tag:base64ciphertext. The validateSSN function at los-app/backend/src/services/identityService.js:32 tests /^\d{4}$/ which will always fail for an encrypted value, causing identity checks to incorrectly report SSN validation failure for all borrowers with encrypted SSN data. The creditService.js:18-19 correctly decrypts these fields before use, but identityService.js does not.

🟡 Cache stampede: concurrent requests trigger redundant DB calls when cache entry expires
In cache.js:30-37, when a cache entry expires, every concurrent request that hits getOrSet between the time the entry expires and the loader completes will each independently call the loader() function. For frequently-accessed data like loan products or branches under 5000+ concurrent users, this causes a 'thundering herd' or cache stampede — potentially dozens of identical DB queries fire simultaneously at TTL expiry. The fix is to store and reuse the pending promise so that concurrent callers coalesce onto a single loader invocation.
Prompt for agents
In los-app/backend/src/config/cache.js, the getOrSet function (lines 30-38) has a cache stampede issue. When a cache entry expires, every concurrent request calls the loader independently. To fix this, add a pending promises map (e.g. `const pending = new Map()`) and in getOrSet, before calling loader(), check if there's already a pending promise for that key. If so, await it. If not, create the promise, store it in pending, await it, store the result in the cache, remove from pending, and return. This ensures only one loader call per key at a time.

🔴 Monthly trend query in dashboard ignores branch/date filters, leaking cross-branch data
In reporting.js:73-83, the monthly trend query uses db.raw() with a hardcoded SQL query against the applications table. Unlike all other queries on this endpoint which use baseQuery.clone() (which includes branch_id, start_date, end_date, and branch manager branch filters applied at lines 12-19), this raw query has no filters at all. This means branch managers see trends from ALL branches (not just their own), and date/branch filters from query parameters are ignored for this metric. This is both a data leak (branch managers see other branches' data) and an inconsistency with the rest of the dashboard.
Prompt for agents
In los-app/backend/src/routes/reporting.js lines 73-83, the monthly trend query bypasses all the filters applied to baseQuery (branch_id, date range, branch_manager auto-filter). Replace the db.raw() call with a query built from baseQuery.clone() to respect the same filters. For example:
const monthlyTrend = await baseQuery.clone()
.select(db.raw("TO_CHAR(created_at, 'YYYY-MM') as month"))
.count('id as count')
.sum('requested_amount as total_amount')
.select(db.raw("COUNT(CASE WHEN status IN ('approved', 'funded', 'servicing') THEN 1 END) as approved_count"))
.where('created_at', '>=', db.raw("NOW() - INTERVAL '6 months'"))
.groupBy(db.raw("TO_CHAR(created_at, 'YYYY-MM')"))
.orderBy('month');
Then use monthlyTrend directly instead of monthlyTrend.rows.

🔴 Admin user update logs password hash in audit trail details
In admin.js:88-101, when an admin updates a user's password, the password_hash is added to the updates object at line 89. This same updates object is then passed directly as details to createAuditLog at line 100. This means the bcrypt password hash is written to the audit_logs table in plaintext JSON. While bcrypt hashes are not reversible, logging credential material to an audit trail accessible by compliance officers violates security best practices and may violate compliance requirements.

🔴 E-sign endpoint allows any non-approved/non-conditionally-approved application to be signed if there are zero conditions
In applications.js:480-489, when the application status is NOT in ['approved', 'conditionally_approved'], the code checks if there are pending conditions. If there are zero pending conditions (including the case where there are zero conditions total), the check passes and e-signing proceeds. This means an application in status submitted, draft, underwriting, declined, or any other non-approved status can be e-signed as long as it has no conditions records. The logic should also reject applications that are not in an approvable state, rather than only checking conditions count.

🟡 SQL injection via unsanitized search query parameter in ILIKE clauses
In los-app/backend/src/routes/applications.js:99 and los-app/backend/src/routes/admin.js:26, user-supplied search query parameter values are interpolated directly into ILIKE patterns using template literals (%${search}%). While Knex parameterizes the value itself, the % wildcards combined with user input allow a user to inject special LIKE pattern characters like % and _ to craft unexpected queries (SQL wildcard injection). More critically, there's no length limit on the search parameter, so a very long search string could degrade performance. The same pattern appears in the audit logs route at admin.js:246 for the action filter.

🔴 Total funded amount ignores all dashboard filters (date range, branch)
In reporting.js:86, the totalFunded query hits the loans table directly with db('loans').sum(...) rather than using baseQuery.clone(). This means the total funded amount metric ignores all dashboard filters (date range, branch_id, branch manager's branch) and always shows the global total across all branches and dates. This is inconsistent with other dashboard metrics that properly use the filtered baseQuery.
Prompt for agents
In los-app/backend/src/routes/reporting.js line 86, the totalFunded query uses db('loans').sum('principal_amount as total').first() which queries the loans table directly without any filters. This means the 'Total Funded' KPI on the executive dashboard always shows the global total regardless of date range or branch filters. To fix, either join the loans table through applications to apply the existing filters, or query from baseQuery.clone() joined to loans. The loans table has application_id which can be joined to the filtered applications query.

Reduces input errors and is more intuitive.<select>dropdown (1–31) that dynamically adjusts based on the selected month and year (e.g., February shows 28 or 29 days, April shows 30). Previously was a plain text input with no day-count awareness.Note: This revision has been superseded by the calendar date picker above, but the ADA work informed the new component's accessibility patterns.

All four chart sections (Volume by State, Volume by Product, Volume by Branch, Status Breakdown) rendered as empty because the data arrays were alwaysundefined. Fixed inExecutiveDashboard.jsx.Bug 2 — Compliance Dashboard adverse actions tab never showed data:

Frontend forms used

Creating or editing state rules would silently send the wrong field names, resulting in no data being saved for rate caps or disclosures. Also fixed adverse action reason code field (reason_codes→decision_reasons) and timestamp field (created_at→decision_at). Fixed across all form inputs, display, and API payloads inComplianceDashboard.jsx.Bug 4 — Reporting dashboard avgTimeToFund ignored branch/date filters:
The
