CWE-180Incorrect Behavior Order: Validate Before Canonicalize

Abstraction: Variant · CVEs in our corpus: 26

The product validates input before it is canonicalized, which prevents the product from detecting data that becomes invalid after the canonicalization step.

This can be used by an attacker to bypass the validation and launch attacks that expose weaknesses that would otherwise be prevented, such as injection.

Cumulative inbound coverage

How completely the frameworks we cross-walk collectively cover this — the verdict is the strongest single mapping (overlapping partials are not summed); breadth shows the corroboration behind it.

Collective: partial · 6 mapping(s) from 1 framework(s): CAPEC 6 (partial)

MITRE ATT&CK techniques this weakness enables

Our own two-way CWE↔ATT&CK cross-walk — a direct mapping with no public source (the CWE→CAPEC→ATT&CK chain leaves most top weaknesses, incl. XSS and SQLi, mapped to nothing).

Direction: ← other covers this; → this covers other (F/M/P = full / mostly / partial). gov = governs / implements (a mandate, not coverage).
