CWE-776Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')
The product uses XML documents and allows their structure to be defined with a Document Type Definition (DTD), but it does not properly control the number of recursive definitions of entities.
If the DTD contains a large number of nested or recursive entities, this can lead to explosive growth of data when parsed, causing a denial of service.

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).
