CVE-2026-116008 in DaybydayCRM
Summary
by MITRE • 10/24/2026
DaybydayCRM through 2.2.1 contains a missing authorization vulnerability in ProjectsController::updateAssign() that allows any authenticated user to reassign projects without the can-assign-new-user-to-project permission. Low-privileged employees can send PATCH or POST requests to /projects/updateassign/{external_id} with a chosen user_assigned_id to redirect project ownership and notifications.

The vulnerability identified in DaybydayCRM versions through 2.2.1 represents a critical failure in access control mechanisms, specifically classified under CWE-862 as Missing Authorization. This flaw resides within the ProjectsController::updateAssign() function, which is responsible for handling requests to reassign project ownership and associated notifications. The core technical issue stems from an insufficient verification of user privileges before executing state-changing operations on sensitive resources. While the application correctly implements authentication to verify that a user has logged in, it fails to enforce role-based access control policies during the authorization phase. Specifically, the system does not validate whether the authenticated actor possesses the can-assign-new-user-to-project permission required for this action. This oversight allows any validly authenticated user, regardless of their administrative level or intended scope within the organization, to manipulate project assignments without restriction.
From an operational perspective, this vulnerability enables low-privileged employees to escalate their influence over critical business workflows by redirecting project ownership and notification streams to arbitrary users. By sending crafted PATCH or POST requests to the endpoint /projects/updateassign/{external_id} with a specified user_assigned_id parameter, attackers can transfer control of projects away from legitimate owners. This capability disrupts operational continuity, as notifications regarding deadlines, updates, and deliverables are redirected to unintended recipients who may not be aware of the project context. Furthermore, this lack of authorization controls facilitates potential data exfiltration or sabotage, as an attacker could assign sensitive projects to external accounts or compromised internal users, thereby bypassing standard oversight mechanisms designed to protect proprietary information and maintain accountability within development teams.
The exploitation of this vulnerability aligns with MITRE ATT&CK technique T1078, Valid Accounts, where adversaries leverage legitimate credentials to perform unauthorized actions that are typically restricted by policy. The ability to reassign projects without proper checks also touches upon CWE-269, Improper Privilege Management, as the application grants capabilities beyond what is appropriate for the user's assigned role. In enterprise environments relying on DaybydayCRM for project management and resource allocation, this flaw undermines the integrity of workflow governance. It allows malicious insiders or compromised accounts to alter the chain of command within projects, potentially leading to missed deadlines, miscommunication among stakeholders, and a breakdown in audit trails that track who is responsible for specific deliverables.
To mitigate this vulnerability, immediate patching to a version newer than 2.2.1 is required if available from the vendor. In the interim, organizations should implement strict input validation and server-side authorization checks within the updateAssign() method to ensure that only users with explicit can-assign-new-user-to-project permissions are permitted to execute reassignment operations. Additionally, deploying a Web Application Firewall with rules targeting unauthorized access attempts on project management endpoints can provide an additional layer of defense by blocking requests from non-administrative accounts attempting to modify assignment parameters. Regular security audits focusing on role-based access control configurations and continuous monitoring for anomalous changes in project ownership are recommended to detect potential exploitation activities early.
