CVE-2026-106105: @quasar App-Vite

High severity, CVSS 8.4. EPSS: 0.1% chance of exploitation in the next 30 days.

Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to @quasar/ssl-certificate 2.1.0, @quasar/cli 5.0.4, and @quasar/app-vite 3.3.0, the @quasar/ssl-certificate utility cached a combined private key and certificate PEM without explicitly applying owner-only filesystem permissions. Another local user able to read the cache can copy the key and impersonate a development TLS endpoint in an environment that trusts the certificate. The generated certificate was also CA-capable, carried unnecessarily broad key usages, and encoded the IPv6 loopback address as a DNS subject alternative name. This issue is fixed in @quasar/ssl-certificate 2.1.0, @quasar/cli 5.0.4, and @quasar/app-vite 3.3.0.

Affected products

• @quasar App-Vite: before 3.3.0 (fixed in 3.3.0)
• @quasar CLI: before 5.0.4 (fixed in 5.0.4)
• @quasar SSL-Certificate: before 2.1.0 (fixed in 2.1.0)
• Quasarframework Quasar: before 2.23.3 (fixed in 2.23.3)
