+### fast-xml-parser: Repeated DOCTYPE declarations reset entity expansion limits
+[GHSA-8r6m-32jq-jx6q](https://github.com/advisories/GHSA-8r6m-32jq-jx6q)
+
+<details>
+<summary>More information</summary>
+
+#### Details
+##### Impact
+`fast-xml-parser` processes multiple "DOCTYPE" declarations within a single XML document. Each declaration passes its entities to `@nodable/entities` through `addInputEntities()`.
+
+`addInputEntities()` resets the entity expansion counters every time it is called. An attacker can therefore insert additional DOCTYPE declarations to repeatedly reset maxTotalExpansions and maxExpandedLength during one parse operation.
+
+This allows a crafted XML document to exceed the configured entity-expansion limits and can cause excessive CPU use, event-loop blocking, memory exhaustion, and process termination.
+
+##### Workarounds
+- Manually check if multiple DOCTYPEs are not present in input contents
+- Update to v5.10.1
+- Keep `processEntity` flag off
+
+#### Severity
+- CVSS Score: 8.7 / 10 (High)
+- Vector String: `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N`
