{"id":"CVE-2019-11747","details":"The \"Forget about this site\" feature in the History pane is intended to remove all saved user data that indicates a user has visited a site. This includes removing any HTTP Strict Transport Security (HSTS) settings received from sites that use it. Due to a bug, sites on the pre-load list also have their HSTS setting removed. On the next visit to that site if the user specifies an http: URL rather than secure https: they will not be protected by the pre-loaded HSTS setting. After that visit the site's HSTS setting will be restored. This vulnerability affects Firefox \u003c 69 and Firefox ESR \u003c 68.1.","modified":"2026-04-16T04:37:49.047109488Z","published":"2019-09-27T18:15:12.507Z","related":["SUSE-SU-2019:14246-1","SUSE-SU-2019:2545-1","SUSE-SU-2019:2620-1","openSUSE-SU-2019:2251-1","openSUSE-SU-2019:2260-1","openSUSE-SU-2024:10600-1","openSUSE-SU-2024:14572-1"],"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html"},{"type":"ADVISORY","url":"https://www.mozilla.org/security/advisories/mfsa2019-25/"},{"type":"ADVISORY","url":"https://www.mozilla.org/security/advisories/mfsa2019-26/"},{"type":"REPORT","url":"https://bugzilla.mozilla.org/show_bug.cgi?id=1564481"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-11747.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"69.0"}]},{"events":[{"introduced":"0"},{"fixed":"68.1.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N"}]}
