CVE-2026-73640Network attack vector

Database disclosure via password-recovery SQL predicate injection

Published Sep 28, 2026 · Updated Sep 28, 2026

Time-based blind SQL injection in Dayforce Payroll R2026.2.0 allows remote attackers to infer data via password recovery GET requests. The password-recovery handler treats a crafted GET parameter as part of a SQL predicate, allowing response delays to encode results from injected queries. Exposure requires a tenant with self-service password reset enabled; the supplied advisory confirms only R2026.2.0 and does not identify the parameter.
