CVE-2026-8649 Overview
CVE-2026-8649 is an improper neutralization of special elements in data query logic vulnerability [CWE-943] in Progress MOVEit Transfer. The flaw resides in the Custom Reports module and allows an authenticated attacker with high privileges to manipulate query logic. Successful exploitation impacts the confidentiality, integrity, and availability of data managed by MOVEit Transfer. The vulnerability affects MOVEit Transfer versions before 2025.0.7 and versions from 2025.1.0 before 2025.1.3. Progress has published fixed releases through the MOVEit Transfer 2026 release notes.
Critical Impact
An authenticated high-privileged user can inject crafted input into Custom Reports query logic to read, alter, or disrupt data across the MOVEit Transfer instance.
Affected Products
- Progress MOVEit Transfer versions before 2025.0.7
- Progress MOVEit Transfer versions from 2025.1.0 before 2025.1.3
- Progress MOVEit Transfer Custom Reports module

Technical Details for CVE-2026-8649
Vulnerability Analysis
The vulnerability exists in the Custom Reports functionality of MOVEit Transfer. Input supplied to the reporting query layer is not properly neutralized before being incorporated into a data query. An attacker with high privileges can supply crafted special characters that alter the intended query structure. This category of flaw is tracked as [CWE-943], covering injection into data query logic beyond classical SQL injection.
Exploitation requires authentication, user interaction, and yields high impact to confidentiality, integrity, and availability. The attack complexity is elevated because the attacker must satisfy privilege and interaction preconditions to reach the vulnerable code path. Once reached, the manipulated query executes with the privileges of the reporting subsystem.
Root Cause
The root cause is insufficient input sanitization within the Custom Reports module before user-controlled values are used to construct data queries. The reporting logic accepts special elements that carry semantic meaning to the underlying query engine. Progress addressed the issue by tightening input handling in MOVEit Transfer 2025.0.7 and 2025.1.3.
Attack Vector
The attack is delivered over the network by an authenticated user with high privileges to the MOVEit Transfer administrative interface. The attacker crafts report parameters or definitions that embed query-altering syntax. When the report is generated, the injected elements are interpreted by the query engine, allowing unauthorized data access, modification, or denial of service. No verified public proof-of-concept code is available at time of writing. Refer to the Progress MOVEit Transfer Release Notes for vendor technical details.
Detection Methods for CVE-2026-8649
Indicators of Compromise
- Unexpected modifications to Custom Report definitions or parameters within MOVEit Transfer audit logs.
- Report executions returning row counts or datasets inconsistent with the report's intended scope.
- Administrative account activity generating Custom Reports outside normal business hours or from unfamiliar source IPs.
- Database or application error entries referencing malformed query syntax originating from the reporting subsystem.
Detection Strategies
- Review MOVEit Transfer audit logs for creation or edits of Custom Reports by administrative users, correlating with authentication events.
- Alert on query errors emitted by the MOVEit Transfer database that reference reporting stored procedures or dynamic query builders.
- Baseline normal Custom Report execution patterns and flag deviations in query duration, result size, or accessed tables.
Monitoring Recommendations
- Forward MOVEit Transfer application, IIS, and database logs to a centralized analytics platform for correlation and retention.
- Monitor privileged MOVEit Transfer account sessions for report authoring activity and multi-factor authentication anomalies.
- Track outbound data volumes from the MOVEit Transfer host to identify staging or exfiltration following report abuse.
How to Mitigate CVE-2026-8649
Immediate Actions Required
- Upgrade MOVEit Transfer to version 2025.0.7 or 2025.1.3 or later, in line with Progress guidance.
- Audit all administrative and high-privileged accounts on the MOVEit Transfer instance and remove unused accounts.
- Rotate credentials for any account with Custom Reports authoring permissions after patching.
- Review Custom Report definitions created or modified prior to patching for unauthorized changes.
Patch Information
Progress has released fixed versions of MOVEit Transfer that remediate CVE-2026-8649. Administrators should apply 2025.0.7 for the 2025.0 branch or 2025.1.3 for the 2025.1 branch. Detailed fix information is documented in the Progress MOVEit Transfer Release Notes.
Workarounds
- Restrict access to the Custom Reports module to a minimal set of trusted administrators until patching is complete.
- Place the MOVEit Transfer administrative interface behind a VPN or IP allowlist to reduce exposure of authenticated attack surface.
- Enforce multi-factor authentication for all accounts holding report authoring or administrative privileges.
- Increase audit log verbosity for report creation and execution events during the remediation window.
