CWE-758Reliance on Undefined, Unspecified, or Implementation-Defined Behavior

Abstraction: Class · CVEs in our corpus: 25

The product uses an API function, data structure, or other entity in a way that relies on properties that are not always guaranteed to hold for that entity.

This can lead to resultant weaknesses when the required properties change, such as when the product is ported to a different platform or if an interaction error (CWE-435) occurs.

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). Drafted by Grok and spot-checked by Claude Opus 4.8.

Direction: ← other covers this; → this covers other (F/M/P = full / mostly / partial).
