This password check is performed through a character-by-character string comparison, and so an attacker who is able to measure the time taken by this check to a high degree of accuracy could potentially use timing differences to gain knowledge of the password. This is [understood to be feasible on a local network, but not on the public internet](https://groups.google.com/d/msg/django-developers/iAaq0pvHXuA/fpUuwjK3i2wJ).\n\nPrivacy settings that restrict access to pages/documents on a per-user or per-group basis (as opposed to a shared password) are unaffected by this vulnerability.\n\nThis has been patched in 2.7.3, 2.8.2, 2.9.","provenance":"source","from":"CVE.org"},"cvss":{"score":6.1,"severity":"MEDIUM","version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:L/A:N","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.0025,"percentile":0.16315,"provenance":"source"},"cwes":[{"id":"CWE-208","name":"Observable Timing Discrepancy"}],"references":[{"url":"https://github.com/wagtail/wagtail/security/advisories/GHSA-jjjr-3jcw-f8v6","tags":["x_refsource_CONFIRM"]},{"url":"https://github.com/wagtail/wagtail/commit/3c030490ed575bb9cd01dfb3a890477dcaeb2edf","tags":["x_refsource_MISC"]},{"url":"https://github.com/wagtail/wagtail/commit/b76ab57ee859732b9cf9287d380493ab24061090","tags":["x_refsource_MISC"]},{"url":"https://github.com/wagtail/wagtail/commit/ba9d424bd1ca5ce1910d3de74f5cc07214fbfb11","tags":["x_refsource_MISC"]},{"url":"https://github.com/wagtail/wagtail/commit/bac3cd0a26b023e595cf2959aae7da15bb5e4340","tags":["x_refsource_MISC"]}],"priority":{"score":7.5,"factors":[{"name":"EPSS percentile","points":3.26},{"name":"CVSS severity","points":4.27}]},"vendorSlug":"wagtail","affectedVersions":[{"vendor":"wagtail","product":"Wagtail","versions":["< 2.7.3",">= 2.8rc1, < 2.8.2","= 2.9rc1"]}],"affected":[{"ecosystem":"PyPI","package":"wagtail","vulnerableRanges":["<2.7.3",">=2.8rc1, <2.8.2",">=2.9rc1, <2.9",">=2.7, <2.7.3",">=2.8, <2.8.2"],"patched":["2.7.3","2.8.2","2.9"],"from":["GHSA-jjjr-3jcw-f8v6","PYSEC-2020-153"],"provenance":"source"}],"euvd":{"id":"EUVD-2020-0236","exploited":false,"provenance":"source"},"lineage":{"packageHistory":[{"cve":"CVE-2020-11001","published":"2020-04-14","fixed":"2.8.1","kev":false,"link":{"from":"CVE-2020-11001","to":"CVE-2020-11037","relation":"successor","confidence":"low","kind":"sequence","evidence":[{"kind":"version-step","provenance":"source","package":"PyPI:wagtail","fromFixed":"2.7.2","toFixed":"2.7.3","daysApart":16}]}},{"cve":"CVE-2020-11037","published":"2020-04-30","fixed":"2.9","kev":false},{"cve":"CVE-2020-15118","published":"2020-07-20","fixed":"2.9.3","kev":false,"link":{"from":"CVE-2020-11037","to":"CVE-2020-15118","relation":"successor","confidence":"low","kind":"sequence","evidence":[{"kind":"version-step","provenance":"source","package":"PyPI:wagtail","fromFixed":"2.9","toFixed":"2.9.3","daysApart":81}]}},{"cve":"CVE-2021-29434","published":"2021-04-19","fixed":"2.12.4","kev":false},{"cve":"CVE-2021-32681","published":"2021-06-17","fixed":"2.13.2","kev":false}],"package":"PyPI:wagtail"}}
