Description
CERT Polska has received a report about vulnerabilities in Dayforce Payroll software and participated in coordination of their disclosure.
The vulnerability CVE-2026-73640: 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.
The vulnerability CVE-2026-73641: 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.
The vulnerability CVE-2026-73642: Dayforce Payroll is vulnerable to Path Traversal in file download functionality. An unauthenticated attacker can sent GET request with file path parameter set to any path including an absolute local file path.
Because vendor contact attempts were unsuccessful, the vulnerabilities have only been confirmed in version R2026.2.0 but may also affect other versions.
