CVE-2026-8800 Overview
CVE-2026-8800 is an Incorrect Authorization vulnerability [CWE-863] in the Audit User module of Progress MOVEit Transfer. The flaw allows an authenticated user with high privileges to access limited confidential information they should not be able to view. The issue affects MOVEit Transfer versions before 2025.0.7 and versions from 2025.1.0 before 2025.1.3. Exploitation requires network access and existing high-level privileges, which constrains real-world exploitability.
Critical Impact
An authorized MOVEit Transfer user can bypass access controls in the Audit User module to read information outside their permission scope, resulting in limited confidentiality loss.
Affected Products
- Progress MOVEit Transfer versions before 2025.0.7
- Progress MOVEit Transfer versions 2025.1.0 through 2025.1.2
- Audit User module component

Technical Details for CVE-2026-8800
Vulnerability Analysis
The vulnerability resides in the Audit User module of MOVEit Transfer, a managed file transfer product used to move sensitive data between systems and partners. The module fails to correctly enforce authorization checks when a privileged user requests audit-related resources. As a result, the application returns data that should be restricted by the caller's assigned role. The scope of exposure is limited to confidentiality; integrity and availability of the system remain unaffected. The attack can be launched over the network against the MOVEit Transfer web interface or API endpoint exposing the Audit User functionality.
Root Cause
The root cause is an incorrect authorization decision [CWE-863] in the Audit User module. The code path performs authentication and verifies that the caller holds a high-privilege role, but does not correctly restrict which audit records or user attributes that role is permitted to read. Missing or incomplete server-side authorization logic allows the request to succeed against data outside the caller's permitted scope.
Attack Vector
Exploitation requires an authenticated account with high privileges on the target MOVEit Transfer instance. The attacker issues a crafted request to the Audit User module over the network and receives audit data belonging to users or resources they are not entitled to view. No user interaction is required and the attack complexity is low. Because the prerequisite is a high-privilege account, exploitation is most relevant to insider misuse or scenarios where a privileged credential has been previously compromised.
No verified public proof-of-concept is available. Refer to the Progress Release Notes 2026 for vendor technical details.
Detection Methods for CVE-2026-8800
Indicators of Compromise
- Unexpected access to Audit User endpoints from administrative or service accounts outside normal operational patterns
- Audit log queries returning volumes of user data that exceed the caller's typical scope of responsibility
- Requests to MOVEit Transfer audit APIs from IP addresses or sessions not associated with routine administration
Detection Strategies
- Enable MOVEit Transfer detailed audit logging and forward events to a centralized log analytics platform for correlation
- Baseline normal Audit User module usage per administrator account and alert on statistical deviations
- Review web server and application logs for repeated calls to Audit User endpoints returning HTTP 200 responses from a single privileged session
Monitoring Recommendations
- Monitor privileged account activity in MOVEit Transfer, especially administrator and auditor roles, for lateral browsing of user records
- Track configuration changes to role assignments and privilege grants within the MOVEit Transfer administrative console
- Correlate MOVEit Transfer audit events with identity provider sign-in logs to identify unusual session origins for privileged users
How to Mitigate CVE-2026-8800
Immediate Actions Required
- Upgrade MOVEit Transfer to version 2025.0.7 or later on the 2025.0.x branch
- Upgrade MOVEit Transfer to version 2025.1.3 or later on the 2025.1.x branch
- Audit all accounts currently assigned high-privilege roles and remove entitlements that are no longer required
- Rotate credentials for administrator accounts if unusual Audit User module activity is observed
Patch Information
Progress has addressed CVE-2026-8800 in MOVEit Transfer 2025.0.7 and 2025.1.3. Full remediation details are documented in the Progress Release Notes 2026. Apply the patch during your next available maintenance window and validate the fix in a staging environment before production rollout.
Workarounds
- Restrict network access to the MOVEit Transfer administrative and audit interfaces to a limited management network
- Reduce the number of accounts holding high-privilege roles until the patch is applied
- Enforce multi-factor authentication on all administrative accounts to reduce the risk of privileged credential abuse
