This occurs because Cache-Control and Vary headers were mishandled.","published":"2020-06-24T23:15:10.590Z","modified":"2026-07-08T05:53:39.034342495Z","cvss":{"score":3.1,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"mediawiki/core","fixedVersion":"1.31.8"},{"ecosystem":"Packagist","name":"mediawiki/core","fixedVersion":"1.33.4"},{"ecosystem":"Packagist","name":"mediawiki/core","fixedVersion":"1.34.2"}],"fix":null,"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EEZIMLJMJS72SJXPYL736XMUAVCRQD2H/"},{"type":"ADVISORY","url":"https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/core/+/REL1_31/RELEASE-NOTES-1.31"},{"type":"ADVISORY","url":"https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/core/+/REL1_33/RELEASE-NOTES-1.33"},{"type":"ADVISORY","url":"https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/core/+/REL1_34/RELEASE-NOTES-1.34"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2020/12/msg00034.html"},{"type":"ADVISORY","url":"https://lists.wikimedia.org/pipermail/wikitech-l/2020-June/093535.html"},{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4767"},{"type":"FIX","url":"https://phabricator.wikimedia.org/T248947"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T05:53:39.034342495Z"}}
