This medium-severity CVE scores 5.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3% (23rd percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
