The sanitizer only attempts to filter SCRIPT elements, which makes it feasible for remote attackers to conduct XSS attacks via (for example) JavaScript code in an attribute of various other elements. An attacker might also exploit a bug in how the SCRIPT string is processed by splitting and nesting them for example.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://aurelia.io","https://github.com/aurelia/templating-resources/blob/0cef07a8cac8e99146d8e1c4b734491bb3dc4724/src/html-sanitizer.js","https://www.gosecure.net/blog/2021/05/12/aurelia-framework-insecure-default-allows-xss/","https://aurelia.io","https://github.com/aurelia/templating-resources/blob/0cef07a8cac8e99146d8e1c4b734491bb3dc4724/src/html-sanitizer.js"],"products":["bluespire:aurelia_framework"],"source":"nvd","synced_at":"2026-10-19T21:18:09.669877188+00:00"},"epss":{"cve":"CVE-2019-10062","score":0.01416,"percentile":0.72774,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-m6j2-v3gq-45r5","url":"https://osv.dev/vulnerability/GHSA-m6j2-v3gq-45r5","summary":"Cross-site Scripting in aurelia-framework","modified":"2023-11-08T04:00:39.374136Z","packages":[{"ecosystem":"npm","name":"aurelia-framework","purl":"pkg:npm/aurelia-framework","ranges":["<1.4.1"],"fixed":["1.4.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
