CVE-2026-81818 in Flowintel
Summary
by MITRE • 08/27/2026
Affected versions of Flowintel contain an authorization flaw in the administrative user-edit API.
The existing authorization check correctly prevented an organization administrator from editing users in another organization, but it did not prevent them from editing a full administrator within their own organization. As a result, an org admin could modify that full administrator account, including changing its password. The upstream commit explicitly describes the issue as:
“Org admin can change the password of a full admin in the same organization.”
The fix adds a higher-privilege boundary check:
if user_to_edit.is_admin(): return ... 403
so organization administrators can no longer modify full administrator accounts.
Version impacted >=3.3.0

Analysis

Flowintel versions starting from 3.3.0 contain an authorization flaw within the administrative user-edit API that allows for privilege escalation through improper access control mechanisms. The vulnerability stems from a gap in the role-based access control logic, where organization administrators are granted permissions to modify user accounts but lack sufficient restrictions when targeting other high-privilege users within their own organizational boundary. While the system correctly prevents an administrator from editing users belonging to different organizations, it fails to enforce strict boundaries between standard administrative roles and full administrator privileges inside the same tenant context. This oversight enables a malicious or compromised organization admin to interact with the user-edit endpoint for any account designated as a full administrator within their scope.
The technical impact of this flaw is significant because it allows an attacker to directly manipulate critical security attributes of privileged accounts, most notably by changing passwords without authorization. By resetting the password of a full administrator, the actor can seize control of that high-privilege session, effectively escalating their own privileges from organization admin to full system administrator within Flowintel. This bypasses standard authentication controls and undermines the principle of least privilege, as lower-level admins gain unrestricted access to sensitive configuration data, user management functions, and potentially other organizational resources protected by higher-tier permissions. The vulnerability aligns with CWE-269 Improper Privilege Management, specifically reflecting scenarios where role boundaries are not strictly enforced during administrative operations.
From a threat modeling perspective using the MITRE ATT&CK framework, this flaw facilitates lateral movement within an application environment and represents a classic case of privilege escalation via insecure direct object references or broken access control on sensitive endpoints. An attacker leveraging this vulnerability could achieve persistent unauthorized access by maintaining control over multiple admin accounts, complicating detection efforts since actions are performed under legitimate administrative credentials. The operational impact includes potential data exfiltration, modification of system configurations, and disruption of services depending on the capabilities granted to full administrators in specific deployments.
To mitigate this risk, organizations running Flowintel versions 3.3.0 or higher must upgrade immediately to a patched version where the fix has been implemented. The resolution introduces an explicit check that denies access if the target user being edited holds admin privileges, returning a forty-three forbidden status code instead of allowing modification. Until upgrading is possible, administrators should enforce strict monitoring on administrative API calls and review audit logs for any unexpected password changes or profile modifications initiated by organization-level admins. Additionally implementing multi-factor authentication for all administrative accounts can reduce the impact if an attacker successfully exploits this flaw to gain initial access to a full admin session.
