Machine-written summary

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

The launch-editor npm package before 2.14.2 has a flaw on Windows where its check that a supplied file exists can be bypassed, and the advisory also lists vite and vite-plus as affected. An attacker who controls the file argument, without needing to create a file, could combine this with a separate escaping issue to run OS commands, but only in apps running on Windows. Upgrade launch-editor to 2.14.2, vite to 6.4.4, 7.3.7, 8.1.6, 8.2.4 or 8.3.3 for its release line, or vite-plus to 1.1.0.
