The configured path was made absolute, but it was not checked before removal. A configuration mistake could therefore target the project root, user home directory, a filesystem root, or another directory outside the project.\n\n## Details\n\nThe build command and mode builders passed the resolved output directory directly to `fs-extra` recursive removal. Existing symlink ancestors were not resolved before deletion either, so a path that appeared to be inside the project could operate on a directory outside it.\n\n`quasar.config` is trusted application code, and no attacker-controlled input reaches `build.distDir` by default. This issue is primarily destructive-build safety hardening. It can become a security boundary when build configuration is generated or influenced by less-trusted automation.\n\n## Impact\n\nRunning a normal Quasar build with an unsafe `build.distDir` can delete data accessible to the build user before compilation begins.\n\n## Remediation\n\nValidate the effective deletion target before every artifact cleanup. Always reject filesystem roots, the user home directory and the project root; resolve existing symlink ancestors; require an explicit `build.allowOutsideProjectDistDir` opt-in for external output directories; and log the exact resolved target before removal.","affected":[{"package":{"name":"@quasar/app-vite","ecosystem":"npm","purl":"pkg:npm/%40quasar/app-vite"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.0.0"},{"fixed":"3.3.0"}]}],"database_specific":{"last_known_affected_version_range":"<= 3.2.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-q9mq-245r-4g93/GHSA-q9mq-245r-4g93.json"}}],"references":[{"type":"WEB","url":"https://github.com/quasarframework/quasar/security/advisories/GHSA-q9mq-245r-4g93"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-106109"},{"type":"WEB","url":"https://github.com/quasarframework/quasar/commit/6c009734b406e246a0855ed060e3a822de8aecc1"},{"type":"PACKAGE","url":"https://github.com/quasarframework/quasar"},{"type":"WEB","url":"https://github.com/quasarframework/quasar/releases/tag/@quasar/app-vite-v3.3.0"}],"database_specific":{"cwe_ids":["CWE-22","CWE-73"],"github_reviewed":true,"github_reviewed_at":"2026-10-07T16:14:35Z","nvd_published_at":"2026-10-06T18:16:52Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:P/PR:H/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
