Due to insufficient validation of administrator-supplied configuration settings via the HTTP API, it is possible for a CouchDB administrator user to escalate their privileges to that of the operating system's user under which CouchDB runs, by bypassing the blacklist of configuration settings that are not allowed to be modified via the HTTP API. This privilege escalation effectively allows a CouchDB admin user to gain arbitrary remote code execution, bypassing CVE-2017-12636 and CVE-2018-8007.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","score":7.2},"cwes":[],"references":["http://www.securityfocus.com/bid/105046","https://lists.apache.org/thread.html/1052ad7a1b32b9756df4f7860f5cb5a96b739f444117325a19a4bf75%40%3Cdev.couchdb.apache.org%3E","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/S5FPHVVU5KMRFKQTJPAM3TBGC7LKCWQS/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/X3JOUCX7LHDV4YWZDQNXT5NTKKRANZQW/","https://security.gentoo.org/glsa/201812-06"],"products":["apache:couchdb"],"source":"nvd","synced_at":"2026-10-19T20:52:03.425131697+00:00"},"epss":{"cve":"CVE-2018-11769","score":0.08426,"percentile":0.94996,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
