CVE-2026-19614: NanoXML 2.2.3 can be tricked to read hidden files

CVE-2026-19614 · published 1 month ago

Summary

The NanoXML library (version 2.2.3) processes XML data with a setting that lets attackers include references to external files or services. This can let a malicious user cause the program to read confidential files or contact internal servers without permission. Disable external entity handling in the library or upgrade to a version where this setting is turned off by default.
