CWE-407Inefficient Algorithmic Complexity
An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.

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: mostly · 3 mapping(s) from 2 framework(s): ATT&CK 2 (mostly) · ASVS 5.0 1 (partial)
NIST 800-53 r5 controls that address this weakness (1)AI
| Control | Title | Family | Why it addresses this CWE |
|---|---|---|---|
SC-5 | Denial-of-service Protection | SC | Addresses inefficient algorithms whose complexity can be exploited for DoS. |
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).
