Sources and claim methodology

Upstream source description

Dayforce Payroll is vulnerable to Reflected XSS in multiple endpoints. An attacker can prepare a specially crafted URL that, when opened, results in arbitrary JavaScript execution in the victim's browser. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version R2026.2.0 but may also affect other versions.
