Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Netron versions up to 9.1.2 are affected by a reflected cross-site scripting flaw in the desktop application, caused by unsanitized node names. An attacker who can get a user to open a crafted model file could hide certain nodes, perform port scanning, or chain a Chrome n-day to achieve remote code execution. Upgrade netron to version 9.1.3, which contains the fix.
