{"schemaVersion":3,"id":"CVE-2023-26268","aliases":["UBUNTU-CVE-2023-26268"],"status":"published","duplicateOf":null,"title":null,"description":"Design documents with matching document IDs, from databases on the same cluster, may share a mutable Javascript environment when using these design document functions:\n  *  validate_doc_update\n\n  *  list\n\n  *  filter\n\n  *  filter views (using view functions as filters)\n\n  *  rewrite\n\n  *  update\n\n\n\nThis doesn't affect map/reduce or search (Dreyfus) index functions.\n\nUsers are recommended to upgrade to a version that is no longer affected by this issue (Apache CouchDB 3.3.2 or 3.2.3).\n\nWorkaround: Avoid using design documents from untrusted sources which may attempt to cache or store data in the Javascript environment.","dates":{"published":"2023-05-02T20:06:09.352Z","modified":"2024-10-15T18:11:19.560Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.3,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":4.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
