{"id":"UBUNTU-CVE-2023-26268","details":"Design documents with matching document IDs, from databases on the same cluster, may share a mutable Javascript environment when using these design document functions:   *  validate_doc_update   *  list   *  filter   *  filter views (using view functions as filters)   *  rewrite   *  update This doesn't affect map/reduce or search (Dreyfus) index functions. Users are recommended to upgrade to a version that is no longer affected by this issue (Apache CouchDB 3.3.2 or 3.2.3). Workaround: Avoid using design documents from untrusted sources which may attempt to cache or store data in the Javascript environment.","modified":"2025-10-24T05:01:51Z","published":"2023-05-02T21:15:00Z","upstream":["CVE-2023-26268"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-26268"},{"type":"REPORT","url":"https://lists.apache.org/thread/ldkqs0nhpmho26bdxf4fon7w75hsq5gl"},{"type":"REPORT","url":"https://docs.couchdb.org/en/stable/cve/2023-26268.html"},{"type":"REPORT","url":"https://lists.apache.org/thread/r2wvjfysg3d92lhhjd1qh3wfr8mlp0pp"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-26268"}],"affected":[{"package":{"name":"couchdb","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/couchdb@1.6.0-0ubuntu7?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.0-0ubuntu7"],"ecosystem_specific":{"binaries":[{"binary_name":"couchdb","binary_version":"1.6.0-0ubuntu7"},{"binary_name":"couchdb-bin","binary_version":"1.6.0-0ubuntu7"},{"binary_version":"1.6.0-0ubuntu7","binary_name":"couchdb-common"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-26268.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:L/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
