CVE-2026-27886— Strapi 路径遍历漏洞

Strapi may leak sensitive data via relational filtering due to lack of query sanitization

Strapi is an open source headless content management system. Strapi versions starting in 4.0.0 and prior to 5.37.0 did not sufficiently sanitize query parameters when filtering content via relational fields. An unauthenticated attacker could use the `where` query parameter on any publicly-accessible content-type with an `updatedBy` (or other admin-relation) field to perform a boolean-oracle attack against private fields on the joined `admin_users` table, including the `resetPasswordToken` field. Extracting an admin reset token via this oracle made full administrative account takeover possible without authentication. When a filter such as `where[updatedBy][resetPasswordToken][$startsWith]=a` was applied to a public Content API endpoint, the underlying query generation performed a `LEFT JOIN` against the `admin_users` table and emitted a `WHERE` clause referencing the joined column. The query parameter sanitization layer did not block operator chains that traversed into relational target schemas the caller had no read permission on, allowing the response count to be used as a one-bit oracle on any admin-table field. The patch in version 5.37.0 introduces explicit query-parameter sanitization at the controller and service boundary via three new primitives: `strictParam`, `addQueryParams`, and `addBodyParams`. Operator chains that traverse into restricted relational targets are now rejected before reaching the database.

Strapi 路径遍历漏洞

Strapi是法国strapi社区的一套开源的内容管理系统（CMS）。 Strapi 4.0.0版本至5.37.0之前版本存在路径遍历漏洞，该漏洞源于通过关系字段过滤内容时未充分清理查询参数，可能导致未经身份验证的攻击者使用where查询参数对admin_users表的私有字段执行布尔预言攻击，提取管理员重置令牌实现账户接管。
