## What is CVE-2026-106101?

CVE-2026-106101 is a low-severity vulnerability in quasarframework quasar, published on 6 Oct 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

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.

Weakness: CWE-843 (Access of Resource Using Incompatible Type)

Affected packages and fixed versions:
- quasar (npm): affected all versions; fixed in 2.32.2
- quasar (npm): affected all versions; fixed in 2.32.2

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
