The API is prone to XML external entity (XXE) injection. By default, XML external entity support is enabled. This issue affects NanoXML: 2.2.3.
AnalysisAI
XML External Entity (XXE) injection in NanoXML 2.2.3 allows low-privileged network attackers to trigger unauthorized interaction with external systems or read internal resources, because the library enables external entity processing by default with no opt-out enforced at the API level. The affected product is identified under CPE cpe:2.3:a:cyberelf:nanoxml:*:*:*:*:*:*:*:* and was reported by TCS-CERT with an ENISA EUVD entry (EUVD-2026-72683). …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker hold low-level authenticated access to an endpoint that accepts XML input and processes it via NanoXML 2.2.3 (PR:L per the CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N) scores 5.3 Medium. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patched version is identified in available data - the reference points to a Thales Group advisory page (https://www.thalesgroup.com/en/search/cybersecurity/cybersecurity-services/cve-2026-19614) rather than a NanoXML release changelog or upstream patch. … Detailed patch versions, workarounds, and compensating controls in full report. |
