Fix misplaced entry_point, critical_operation, and trace fields for n8n-related entries that were flagged during human review (verify=0). Changes per entry: entry-00099 (CVE-2026-1470, with-statement bypass): critical_operation: expression-sandboxing.ts:244 → expression.ts:472 A sanitizer function declaration is a defense mechanism, not the vulnerability trigger. Moved to the code execution sink where the bypassed expression is compiled and executed. entry-00100 (CVE-2026-1470, __sanitize shadowing bypass): critical_operation: expression-sandboxing.ts:330-336 → expression.ts:472 Same rationale: sanitizer function body → shared RCE sink. entry-00103 (CVE-2026-25051, webhook XSS/CSP bypass): entry_point: webhook-helpers.ts:615 (closing brace '}') → webhook-request-handler.ts:148 (user header injection) critical_operation: html-sandbox.ts:20 (toLowerCase bug line) → webhook-request-handler.ts:153 (CSP bypass decision) Closing brace had no semantic value. CSP skip decision point better represents where the vulnerability manifests. entry-00176 (CVE-2026-27494, Python __objclass__ sandbox escape): critical_operation: constants.py:126 (BLOCKED_ATTRIBUTES = {) → task_analyzer.py:63 (visit_Attribute method) A static set literal is data, not an operation. Moved to the actual security check that uses this incomplete blocklist. entry-00511 (CVE-2026-25049, extend→constructor path A): entry_point: expression.ts:485 (data.extend = extend) → expression.ts:451 (resolveSimpleParameterValue) Internal sandbox capability registration is not an external input boundary. Moved to the user-expression entry point. entry-00512 (CVE-2026-25049, __sanitize overwrite path B): entry_point: expression.ts:524 (renderExpression) → expression.ts:451 (resolveSimpleParameterValue) Internal bridge method is not an external input boundary. All line numbers verified against the 4 vulnerable commits in github.com/n8n-io/n8n. verify flag set to 1 for all 6 entries. SCHEMA.md invariants preserved.

Fix misplaced entry_point, critical_operation, and trace fields for n8n-related entries that were flagged during human review (verify=0).
Changes per entry:
entry-00099 (CVE-2026-1470, with-statement bypass):
critical_operation: expression-sandboxing.ts:244 → expression.ts:472
A sanitizer function declaration is a defense mechanism, not the
vulnerability trigger. Moved to the code execution sink where the
bypassed expression is compiled and executed.
entry-00100 (CVE-2026-1470, __sanitize shadowing bypass):
critical_operation: expression-sandboxing.ts:330-336 → expression.ts:472
Same rationale: sanitizer function body → shared RCE sink.
entry-00103 (CVE-2026-25051, webhook XSS/CSP bypass):
entry_point: webhook-helpers.ts:615 (closing brace '}')
→ webhook-request-handler.ts:148 (user header injection)
critical_operation: html-sandbox.ts:20 (toLowerCase bug line)
→ webhook-request-handler.ts:153 (CSP bypass decision)
Closing brace had no semantic value. CSP skip decision point better
represents where the vulnerability manifests.
entry-00176 (CVE-2026-27494, Python objclass sandbox escape):
critical_operation: constants.py:126 (BLOCKED_ATTRIBUTES = {)
→ task_analyzer.py:63 (visit_Attribute method)
A static set literal is data, not an operation. Moved to the actual
security check that uses this incomplete blocklist.
entry-00511 (CVE-2026-25049, extend→constructor path A):
entry_point: expression.ts:485 (data.extend = extend)
→ expression.ts:451 (resolveSimpleParameterValue)
Internal sandbox capability registration is not an external input
boundary. Moved to the user-expression entry point.
entry-00512 (CVE-2026-25049, __sanitize overwrite path B):
entry_point: expression.ts:524 (renderExpression)
→ expression.ts:451 (resolveSimpleParameterValue)
Internal bridge method is not an external input boundary.
