Summary

The Incutio XML-RPC (IXR) Library, as used in WordPress before 3.9.2 and Drupal 6.x before 6.33 and 7.x before 7.31, does not limit the number of elements in an XML document, which allows remote attackers to cause a denial of service (CPU consumption) via a large document, a different vulnerability than CVE-2014-5265.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
