20
FAUCET Score

CVE-2019-19327 is an HTML injection vulnerability in the ui/ResultView.js component of the Wikibase Wikidata Query Service GUI, affecting versions prior to 0.3.6-SNAPSHOT 2019-11-07. This medium-severity vulnerability (CVSS 6.1) allows an unauthenticated attacker to inject HTML when result counts and milliseconds are reported, requiring user interaction. While the potential impact is low for confidentiality and integrity, there is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this CVE. It's important to note that the affected GUI code is no longer bundled with newer Wikibase Wikidata Query Service snapshots.
