CVE-2026-106108

Quasar Framework: App Vite SSG page output paths can escape the configured distribution directory

Quasar Framework is a framework for building high-performance Vue.js user interfaces. From 3.1.0 until 3.3.0, @quasar/app-vite SSG page definitions returned by getSsgPages() could supply dir and filename values that were joined to build.distDir without verifying the final destination. Parent traversal or an existing symlink below the distribution directory could create new HTML files or directories outside the output tree with the build user's permissions. Application configuration and SSG page definitions are trusted by default, so exploitation requires a build process that derives them from external or otherwise less-trusted content; existing files remain protected by the renderer's no-overwrite behavior. This issue is fixed in version 3.3.0.

Quasar Framework: Path Traversal / Arbitrary File Write via crafted Icon Genie profile

Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to @quasar/icongenie 6.1.1, the icongenie generate --profile command accepted folder and name values from a user-supplied profile without constraining the resolved destination to the Quasar project directory. icongenie/lib/utils/get-assets-files.js joined those values with appDir, while icongenie/lib/utils/validate-profile-object.js required only non-empty strings, allowing parent-directory traversal. A developer who runs a crafted profile can cause generated image content to be written or overwritten at any path writable by that user, potentially modifying shell startup files, build scripts, or other executable configuration. This issue is fixed in version 6.1.1.

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

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.

Quasar Framework: SSR/SSG dev error page discloses the full shell environment and its </script> escape is bypassable

Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to @quasar/render-ssr-error 2.2.4 and @quasar/app-vite 3.3.0, renderSSRError() in utils/render-ssr-error/src/index.js used diagnostic data from utils/render-ssr-error/src/env.js to serialize process.env, request headers, and cookies into the HTTP page returned by serve.devError(), while the development server listened on all interfaces by default. Any network-adjacent client that reaches an SSR or SSG render failure through this development-only error path can obtain shell environment secrets. The renderer escaped only one exact lowercase script closing-tag spelling, so case variants and valid closing-tag delimiter variants in reflected diagnostic data could terminate the script element and inject markup; executing the injected code in a developer browser additionally requires the payload to accompany that developer's request. This issue is fixed in @quasar/render-ssr-error 2.2.4 and @quasar/app-vite 3.3.0.

Quasar Framework: App Vite SSR and SSG nonce attributes are not safely constrained

Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to 3.3.0, several @quasar/app-vite SSR and SSG rendering paths interpolated ssrContext.nonce directly into quoted HTML attributes. An application that derives or overrides this value with attacker-controlled data can allow a quote to terminate the nonce attribute and inject additional attributes or markup into generated HTML across development and production SSR or SSG output. Cryptographically generated base64 or base64url nonces are not affected because they lack HTML attribute delimiters. This issue is fixed in version 3.3.0.

Quasar Framework: App Vite build cleanup can recursively remove unsafe configured output directories

Quasar Framework is a framework for building high-performance Vue.js user interfaces. From 1.0.0 until 3.3.0, @quasar/app-vite recursively removed the resolved build.distDir before building without rejecting the project root, user home directory, filesystem roots, or symlink-resolved external directories. An unsafe trusted configuration can delete data writable by the build user before compilation begins. No attacker-controlled input reaches build.distDir by default, so exploitation requires compromised or less-trusted automation to influence build configuration, or a developer to run a mistaken configuration. This issue is fixed in version 3.3.0.

Quasar Framework: Super-linear regex backtracking on User-Agent lets one request stall a Quasar SSR server

Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to 2.23.3, Platform.parseSSR() passed an unbounded User-Agent request header to getMatch() in ui/src/plugins/platform/Platform.js, whose browser-detection expressions combined greedy captures with repeated unbounded scans. Platform belongs to autoInstalledPlugins, so this parsing occurs before routing for every SSR request. A crafted unauthenticated request containing repeated version tokens without a terminating Safari token causes super-linear backtracking and blocks the Node.js event loop, delaying every other SSR request. SPA, PWA, Electron, Cordova, Capacitor, browser-extension, and static-site-generation targets are not affected because they do not parse an attacker-controlled request header through this path. This issue is fixed in version 2.23.3.

Quasar Framework: DOM Clobbering in Quasar openURL() SafariViewController Integration Causes Client-Side Denial of Service

Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to 2.32.2, the openURL() utility in ui/src/utils/open-url/open-url.js trusted window.SafariViewController whenever that global existed in an iOS environment. Attacker-controlled HTML rendered by components such as QEditor can create a named SafariViewController element, causing browser named-property resolution to replace the expected native bridge object. A later openURL() call then invokes isAvailable() on the element, throws a TypeError, and disrupts external navigation, login redirects, payment redirects, and other URL-opening workflows. QSelect and QChatMessage HTML-rendering configurations can expose the same trigger when they render attacker-controlled HTML. This issue is fixed in version 2.32.2.

Quasar Framework: Stored/Reflected XSS via unescaped SSR meta tag rendering in getHead()

Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to 2.22.0, the SSR-only getHead() serializer in ui/src/plugins/meta/Meta.js used getAttr() to interpolate values supplied through useMeta() into title, meta, link, and script markup without HTML text or quoted-attribute encoding. injectServerMeta() appended that output to the raw server-rendered response. An attacker who can influence dynamic page metadata, such as a post title, product name, excerpt, or display name, can terminate the intended HTML context and inject executable markup before hydration. The client-side apply() path is not affected because it uses DOM APIs that encode attributes. This issue is fixed in version 2.22.0.

Quasar Framework: Prototype pollution in Quasar extend() utility

Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to 2.22.0, the public extend() utility in ui/src/utils/extend/extend.js recursively copied attacker-controlled object keys during extend(true, target, source) deep merges without rejecting an own __proto__ property. The merge could descend into the prototype object and write attacker-controlled properties to Object.prototype in the same JavaScript process. Applications that passed user-controlled or partially user-controlled objects to extend() could experience logic bypass, unsafe default-option injection, denial of service, or other application-specific impact when polluted properties were later consumed. This issue is fixed in version 2.22.0.
