{"id":"CVE-2026-113666","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-113666","generatedAt":"2026-10-28T01:53:33.065Z","title":"ApostropheCMS is an open-source Node.js content management system.","description":"ApostropheCMS is an open-source Node.js content management system. Prior to 1.1.0 of db-connect and 4.33.0 of ApostropheCMS, an account with view-draft access can submit a projection exclusion path that traverses through a constructor prototype chain to a shared prototype member when a consumer uses a SQLite, PostgreSQL, or multipostgres adapter and has a matching document. Every editing role has view-draft access, while guestApiAccess broadens this prerequisite to any logged-in account. The unsetNestedField helper then deletes the shared runtime member, causing persistent process-wide integrity and availability effects; the default MongoDB adapter is not affected. This issue is fixed in db-connect 1.1.0 and ApostropheCMS 4.33.0.","published":"2026-10-20T18:17:20.000Z","lastModified":"2026-10-20T19:53:10.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H"},"cwe":["CWE-400","CWE-1321"],"affected":[],"epss":{"score":0.00444,"percentile":0.38322,"date":"2026-10-26","history":[{"date":"2026-10-21","score":0.00444,"percentile":0.3748}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.44%).
