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.","state":0,"publishedAt":"2026-10-20T17:25:44.574+00:00","modifiedAt":"2026-10-20T17:43:12.999+00:00","affected":[{"ecosystem":"Vendor product","name":"apostrophe","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"apostrophecms\",\n                    \"product\": \"apostrophe\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.33.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"db-connect","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"@apostrophecms\",\n                    \"product\": \"db-connect\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.1.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-j5rq-xfvr-p969","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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-113666","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-113666","identifiers":["CVE-2026-113666"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
