In general, Ember.js escapes or strips any user-supplied content before inserting it in strings that will be sent to innerHTML. However, the tagName property of an Ember.View was inserted into such a string without being sanitized. This means that if an application assigns a view's tagName to user-supplied data, a specially-crafted payload could execute arbitrary JavaScript in the context of the current domain ("XSS"). This vulnerability only affects applications that assign or bind user-provided content to tagName.
CVE-2013-4170
This medium-severity CVE scores 6.1 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 44% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
