CVE-2026-118510：Laravel MongoDB `whereDoesntHave` 失效，數字字串 ID 造成拒絕記錄遺漏

A type-handling flaw in the relationship query building of this MongoDB integration library can cause a check for the absence of a related record to be compiled with an identifier of the wrong data type. In an application that relies on such a check to decide which documents a request may see or act on, a user with basic privileges may be served, may change, or may remove documents that the check was intended to withhold. The failure is silent and produces no error.
