CVE-2026-86815— BackWPup 5.2.2 - 5.7.4 - BackWPup Jobs Checker+ Database Backup Exfiltration via Missing Authorization on Job REST Routes

Quick assessment

Affected
Unknown BackWPup
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 5.7.5 版本之前的 BackWPup WordPress 插件中，对负责作业（job）、备份目标（backup-destination）和备份执行（backup-execution）管理的多个 REST API 路由的访问限制不够严格。这使得被管理员分配了 BackWPup 插件定义的受限角色的用户，能够创建并运行备份作业，并将完整的数据库备份导出到攻击者控制的目标位置（从而造成数据泄露）。
