{"cve":"CVE-2026-113666","nvd":{"published":"2026-10-20T18:17:20.127","modified":"2026-10-20T19:53:10.247","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H","score":7.1},"cwes":["CWE-400","CWE-1321"],"references":["https://github.com/apostrophecms/apostrophe/commit/9500b8b0e1d630d5e07fbb5fd2c25ed0943845ce","https://github.com/apostrophecms/apostrophe/commit/f84fd41cbf6c22eb8d0008fc9c25df1f7130b350","https://github.com/apostrophecms/apostrophe/releases/tag/@apostrophecms/db-connect@1.1.0","https://github.com/apostrophecms/apostrophe/releases/tag/apostrophe@4.33.0","https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-j5rq-xfvr-p969"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-113666","score":0.00444,"percentile":0.38298,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-j5rq-xfvr-p969","url":"https://osv.dev/vulnerability/GHSA-j5rq-xfvr-p969","summary":"ApostropheCMS: Authenticated projection-exclusion prototype-member deletion in @apostrophecms/db-connect causes process-wide denial of service","modified":"2026-10-20T18:15:04.524962165Z","packages":[{"ecosystem":"npm","name":"@apostrophecms/db-connect","purl":"pkg:npm/%40apostrophecms/db-connect","ranges":["<1.1.0"],"fixed":["1.1.0"]},{"ecosystem":"npm","name":"apostrophe","purl":"pkg:npm/apostrophe","ranges":["<4.33.0"],"fixed":["4.33.0"]}]}],"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).
