Insufficient type checks were employed prior to casting input data in SimpleXMLElement_exportNode and simplexml_import_dom. This issue affects HHVM versions prior to 3.9.5, all versions between 3.10.0 and 3.12.3 (inclusive), and all versions between 3.13.0 and 3.14.1 (inclusive).
Affected
Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.
v < 3.9.53.10.0 ≤ v ≤ 3.12.33.13.0 ≤ v ≤ 3.14.1
Affected range stops below 3.9.5, so it looks safe — our inference, not a vendor statement
