This does not directly lead to a security issue, yet it might aid attackers in their efforts to exploit other problems. The flaws unnecessarily make the servers more prone to Clickjacking, channel downgrade attacks and other similar client-based attack vectors.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-1021","CWE-358"],"references":["https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1728","https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1728"],"products":["quarkus:quarkus","redhat:keycloak"],"source":"nvd","synced_at":"2026-10-19T21:03:08.679916934+00:00"},"epss":{"cve":"CVE-2020-1728","score":0.00783,"percentile":0.56039,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-3gg7-9q2x-79fc","url":"https://osv.dev/vulnerability/GHSA-3gg7-9q2x-79fc","summary":"Improper Restriction of Rendered UI Layers or Frames in Keycloak","modified":"2024-12-02T05:33:56.687490Z","packages":[{"ecosystem":"Maven","name":"org.keycloak:keycloak-core","purl":"pkg:maven/org.keycloak/keycloak-core","ranges":["<=9.0.3"],"fixed":[]}]}],"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).
