CVE-2026-19579 in Snipe-IT
Summary
by MITRE • 08/12/2026
Snipe-IT before 8.6.0 contains an authorization bypass (insecure direct object reference) in the asset checkout-request cancellation endpoint. The cancel_by_admin and requestingUser values are read from user-controlled URL path segments and used without a server-side authorization check, so any authenticated, low-privileged user can supply a non-empty cancel_by_admin value to bypass the request-ownership check and cancel another user's pending checkout request. Because asset and user identifiers are sequential integers, an attacker can enumerate them to cancel every pending checkout request, disrupting the asset-request workflow. This is fixed in Snipe-IT 8.6.0.

The vulnerability identified in Snipe-IT versions prior to 8.6.0 represents a critical authorization bypass flaw classified as an insecure direct object reference or idor vulnerability. This weakness exists within the asset checkout-request cancellation endpoint where the system fails to properly validate user permissions before processing cancellation requests. The flaw allows malicious actors to manipulate URL path segments containing cancel_by_admin and requestingUser parameters, effectively circumventing the intended access controls that should restrict cancellation operations to the original requester or authorized administrators.
The technical implementation of this vulnerability stems from improper server-side validation mechanisms where the application directly trusts input values from URL path segments without performing adequate authorization checks. When a low-privileged authenticated user supplies a non-empty cancel_by_admin value in the request, the system processes this input without verifying whether the requesting user has sufficient privileges to cancel another user's checkout request. This design flaw creates a direct object reference vulnerability where the application relies on client-supplied identifiers rather than maintaining proper access control boundaries.
The operational impact of this authorization bypass extends beyond simple privilege escalation, as it enables attackers to enumerate sequential integer identifiers for both assets and users within the system. Since these identifiers follow predictable numerical patterns, an attacker can systematically test various values to identify valid checkout requests belonging to other users. This enumeration capability allows for mass cancellation of pending checkout requests, effectively disrupting the entire asset management workflow and potentially causing operational downtime for legitimate users who depend on the system for asset allocation.
This vulnerability aligns with CWE-285, which specifically addresses improper authorization in software systems, and maps to ATT&CK technique T1078.004 related to valid accounts and privilege escalation through unauthorized access to resources. The flaw demonstrates poor input validation and access control implementation practices that violate fundamental security principles of least privilege and proper authorization checking. Organizations using affected versions of Snipe-IT face significant risk of workflow disruption, potential asset mismanagement, and unauthorized interference with legitimate business processes.
The mitigation strategy requires implementing robust server-side authorization checks that validate user permissions before processing any cancellation requests, regardless of input values supplied in URL parameters. System administrators should immediately upgrade to Snipe-IT version 8.6.0 or later where this vulnerability has been addressed through proper access control enforcement. Additional protective measures include implementing rate limiting on checkout request operations, logging all cancellation activities for audit purposes, and conducting regular security assessments to identify similar authorization bypass vulnerabilities in other application components.
