{"id":"CVE-2026-106102","published":"2026-10-06T17:17:24.270","lastModified":"2026-10-06T20:03:40.690","description":"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.","cvssScore":10,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N","cwes":["CWE-79","CWE-116"],"vendors":[],"products":[],"references":[{"url":"https://github.com/quasarframework/quasar/commit/11505afe5b5218f2c468f130181815b898fd1e40","tags":[]},{"url":"https://github.com/quasarframework/quasar/releases/tag/quasar-v2.22.0","tags":[]},{"url":"https://github.com/quasarframework/quasar/security/advisories/GHSA-pq96-jpmf-w254","tags":[]}],"exploitRefs":[{"url":"https://github.com/quasarframework/quasar/commit/11505afe5b5218f2c468f130181815b898fd1e40","tags":[]},{"url":"https://github.com/quasarframework/quasar/releases/tag/quasar-v2.22.0","tags":[]},{"url":"https://github.com/quasarframework/quasar/security/advisories/GHSA-pq96-jpmf-w254","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows an attacker to inject executable markup by manipulating metadata, potentially leading to code execution or data exfiltration.","exploitability":"Exploitation is moderately hard as it requires the attacker to influence dynamic page metadata, but preconditions are common in many web applications.","blast_radius":"If exploited, the impact could be severe, as it could lead to arbitrary code execution on the client side during hydration.","remediation":"Upgrade to Quasar Framework version 2.22.0 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","web","ssrf","metadata"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-07T08:42:47.853Z"}}
