Vulnerability from github – Published: 2026-09-28 15:31 – Updated: 2026-10-13 15:31

Details

Dayforce Payroll is vulnerable to Time Based-Blind SQL Injection in password recovery functionality. The unauthenticated attacker can prepare GET request with one of the parameters filled in with an arbitrary SQL query. The parameter is interpreted as part of SQL predicate resulting in Time-Based Blind SQL Injection. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version R2026.2.0 but may also affect other versions.

Severity

9.3 (Critical)


                  
                    CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N
