CVE-2026-19871 in Prospero Flow CRM
Summary
by MITRE • 08/14/2026
Use of Hard-coded Credentials in the human resources component in Roskus Prospero Flow CRM before 5.15.9 allows unauthenticated remote attackers to authenticate as any employee onboarded through the standard flow, knowing only their email address, because the employee save controller falls back to the literal password "changeme" and the onboarding form provides no password field.

The vulnerability in Roskus Prospero Flow CRM affects the human resources component where hard-coded credentials are present in the employee onboarding process. This represents a critical security flaw that allows unauthenticated remote attackers to gain unauthorized access to employee accounts by leveraging a hardcoded password value. The specific technical implementation involves the employee save controller which defaults to using the literal password "changeme" when no password is provided during the standard onboarding workflow. This design decision creates an inherent security weakness where the system does not require or validate passwords during the initial employee setup process, effectively providing a backdoor authentication mechanism.
The operational impact of this vulnerability extends beyond simple unauthorized access as it enables attackers to impersonate any employee within the organization who has been onboarded through the standard flow. Since the attacker only needs to know the target employee's email address to exploit this weakness, the attack surface becomes significantly broader than typical credential-based attacks. This vulnerability directly violates multiple security principles including the principle of least privilege and secure default configurations. The flaw essentially creates a persistent authentication mechanism that remains active regardless of proper password management procedures or security policies.
This vulnerability maps directly to CWE-798, which addresses the use of hard-coded credentials in software applications, and aligns with ATT&CK technique T1078.004 for valid accounts using default passwords. The attack vector is particularly concerning as it requires minimal information gathering from attackers who only need email addresses to begin exploitation attempts. The system's failure to implement proper password validation or generation mechanisms during employee onboarding creates a persistent security risk that affects all employees who have been onboarded through this vulnerable process.
Organizations using this version of Roskus Prospero Flow CRM face significant risks including data theft, unauthorized access to sensitive employee information, potential lateral movement within the network, and possible compliance violations. The recommended mitigation involves updating to version 5.15.9 or later where the hardcoded credentials have been removed from the employee save controller. Additionally, administrators should implement proper password policies for existing employee accounts, enforce multi-factor authentication where possible, and conduct thorough security audits of all authentication mechanisms within the system. The vulnerability also highlights the importance of implementing secure development practices including proper input validation, secure credential management, and avoiding hardcoded values in production code.
