Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Quasar's @quasar/app-vite package, versions 3.1.0 up to but not including 3.3.0, can let SSG page output paths escape the configured build.distDir directory when custom dir or filename values are used. An attacker would need to influence an app's SSG page definitions, such as by deriving them from untrusted content or compromising the build configuration, and could then create new files and directories outside the build output during quasar build -m ssg. Upgrade @quasar/app-vite to version 3.3.0 or later.
