Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Dayforce 薪酬系统存在基于时间的盲注 SQL 注入（Time-Based Blind SQL Injection）漏洞，该漏洞存在于密码恢复功能中。未认证的 attackers 可以构造一个 GET 请求，并在其中一个参数中填充任意的 SQL 查询语句。由于该参数被当作 SQL 谓词（predicate）的一部分进行解析，从而导致发生基于时间的盲注 SQL 注入攻击。 由于未能成功联系到供应商，该漏洞目前仅在 R2026.2.0 版本中确认存在，但其他版本也可能受到影响。
