SCA: security update for quasar (GHSA-3r53-75j5-3g7j)

medium Tenable Self-Hosted Container Security Plugin ID 445364

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-73647)

Solution

Update the quasar library and its related packages to version 2.22.0 or later.
