{"id":"CVE-2020-11037","aliases":["GHSA-jjjr-3jcw-f8v6","PYSEC-2020-153"],"url":"https://o3.security/vulnerability/CVE-2020-11037","summary":"Potential Observable Timing Discrepancy in Wagtail","details":"In Wagtail before versions 2.7.3 and 2.8.2, a potential timing attack exists on pages or documents that have been protected with a shared password through Wagtail's \"Privacy\" controls. 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.","published":"2020-04-30T23:15:11.887Z","modified":"2026-07-09T01:06:35.336624Z","cvss":{"score":4.7,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"wagtail","fixedVersion":"2.7.3"},{"ecosystem":"PyPI","name":"wagtail","fixedVersion":"2.8.2"},{"ecosystem":"PyPI","name":"wagtail","fixedVersion":"2.9"}],"fix":{"url":"https://github.com/wagtail/wagtail/commit/3c030490ed575bb9cd01dfb3a890477dcaeb2edf","label":"wagtail/wagtail@3c03049"},"references":[{"type":"ADVISORY","url":"https://github.com/wagtail/wagtail/security/advisories/GHSA-jjjr-3jcw-f8v6"},{"type":"FIX","url":"https://github.com/wagtail/wagtail/commit/3c030490ed575bb9cd01dfb3a890477dcaeb2edf"},{"type":"FIX","url":"https://github.com/wagtail/wagtail/commit/b76ab57ee859732b9cf9287d380493ab24061090"},{"type":"FIX","url":"https://github.com/wagtail/wagtail/commit/ba9d424bd1ca5ce1910d3de74f5cc07214fbfb11"},{"type":"FIX","url":"https://github.com/wagtail/wagtail/commit/bac3cd0a26b023e595cf2959aae7da15bb5e4340"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T01:06:35.336624Z"}}
