Documented Gaps (Accepted Risk)
The following vectors are not fully blocked by current controls. Each is documented
here as an accepted risk with the mitigating factors noted.
| # |
Vector |
Why not fully blocked |
Mitigation in place |
| GAP-01 |
Unicode homoglyph attacks (Cyrillic і for i) |
Regex matches ASCII only |
Bedrock Guardrails (ML-based) catches most variants |
| GAP-02 |
Zero-width character injection mid-keyword |
Not in current pattern set |
Bedrock Guardrails provides secondary coverage |
| GAP-03 |
Elaborate fictional framing (for a school project...) |
Context-free regex cannot reason about framing |
System prompt hardening + LLM restrictions |
| GAP-04 |
Multi-language injection (ignorieren Sie alle Anweisungen) |
Patterns are English-only |
Low relevance for this profile; Bedrock Guardrails |
| GAP-05 |
Adversarial paraphrase (semantically equivalent, different phrasing) |
Heuristic has finite patterns |
Bedrock Guardrails trains on semantic similarity |
