GHSA-pq96-jpmf-w254: quasar (CVE-2026-106102)

Package	Ecosystem	Affected	Fixed in
quasar	npm	<2.22.0	2.22.0

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Quasar framework versions before 2.22.0 render page title and meta/link/script tag values into server-side HTML without escaping, so text passed to useMeta() can break out of its tag and inject markup, including scripts. An attacker who can influence that text, such as a blog title or a user display name, can get script to run in the origin of every visitor to the affected page, with no authentication required. Upgrade the quasar package to version 2.22.0 or later.
