CVE-2026-88027— Mass deletion and overwrite of embedded documents via query-operator injection in embedded record keys in MongoDB integration for Laravel

Quick assessment

Affected
MongoDB Laravel MongoDB (PHP)
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Laravel 中，MongoDB 集成模块在处理嵌入式文档关系时，若未正确中和数据查询逻辑中的特殊字符，可能导致调用者提供的嵌入式记录标识符被解释为查询条件，而非作为字面量标识符。能够影响此类标识符的已认证用户可能删除目标记录中的所有嵌入式文档，或覆盖非目标的其他嵌入式文档。
