Quasar Framework: Development TLS private keys are cached with overly permissive filesystem permissions

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.

Published

The `@quasar/ssl-certificate` development utility caches a combined PEM containing a generated private key and certificate without explicitly restricting its filesystem permissions. On systems with a typical process umask, the PEM can be readable by other local users. A local attacker with filesystem access could copy and reuse the private key to impersonate a development TLS endpoint in an environment that trusts the certificate. The generated certificate was also unnecessarily CA-capable and included broad key usages beyond its localhost HTTPS purpose. Its IPv6 loopback entry was encoded as a DNS name rather than an IP subject alternative name. The remediation writes and repairs the cached PEM with owner-only permissions on supported platforms, generates a non-CA server-auth leaf certificate with constrained key usage, corrects the IPv6 loopback SAN, and bases cache expiry on content modification time so permission metadata changes cannot extend the certificate lifetime. This issue does not expose the key remotely by itself; exploitation requires another local user to be able to read the cached PEM file.
