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.

Lotus 0.10.2 及更早版本存在一个身份验证不当漏洞，该漏洞位于 Go 事件摄入中间件中。该中间件在验证 API 密钥时仅检查密钥前缀，而未将密钥与存储的哈希值（hashed_key）进行比对。攻击者若知晓或获取了 API 密钥的前缀，即可冒充相应组织向 POST /api/track/ 接口提交使用事件，从而篡改该组织的计量使用数据和计费信息。
