CVE-2026-69144 in SuiteCRM
Summary
by MITRE • 11/05/2026
SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, download.php checks authorization against a Documents bean before resolving whether the supplied identifier is a document_revisions.id. When a revision UUID is submitted with type=Documents, the check targets an empty Documents bean; the revision is then resolved and served without checking its parent document. A low-privileged authenticated user can use this identifier confusion to download administrator-owned or otherwise protected documents. This issue is fixed in versions 7.15.2 and 8.10.2.

SuiteCRM, a widely deployed open-source Customer Relationship Management platform, contains a critical authorization bypass vulnerability within its document management subsystem prior to version 7.15.2 and 8.10.2. The flaw resides in the download.php script, which is responsible for serving file attachments associated with various CRM entities. Under normal operational conditions, this script validates user permissions against specific business objects before allowing access to sensitive data files. However, a logic error occurs when handling document revisions due to an identifier confusion mechanism that fails to properly correlate revision identifiers with their parent documents during the authorization check phase.
The technical root cause involves how the application resolves object identities for security validation. When a request is made specifying type=Documents and providing a specific revision UUID, the system initially attempts to load a Documents bean using this identifier. Because the supplied value corresponds to a document_revisions.id rather than a documents.id, the lookup fails or returns an empty or null bean state. Crucially, the authorization logic proceeds based on this incomplete object context without subsequently verifying that the requested resource belongs to a parent document owned by or accessible to the authenticated user. This oversight allows the script to bypass the intended access control checks entirely for revision files.
This vulnerability enables low-privileged authenticated users to perform unauthorized data exfiltration of administrator-owned documents and other protected assets. By manipulating the identifier passed in the request, an attacker can retrieve sensitive business information such as contracts, financial records, or customer personal data that should be restricted based on role-based access controls. The impact is severe because it undermines the fundamental security model of the application, allowing privilege escalation from a standard user to effectively gaining read-access equivalent to higher-privileged roles regarding specific file resources. This aligns with CWE-284 Improper Access Control and represents an Object Reference Manipulation flaw where the system fails to ensure that object references map correctly to intended access permissions.
From a threat intelligence perspective, this vulnerability facilitates data leakage scenarios often associated with ATT&CK technique T1005 Data from Local System or T1530 Data from Cloud Storage if deployed in cloud environments. Attackers can automate the enumeration of revision IDs to systematically download large volumes of sensitive documents without triggering typical intrusion detection alerts related to brute-force authentication attempts, as valid credentials are used throughout the exploitation process. The lack of proper parent-child relationship validation during file serving creates a silent data breach vector that is difficult to detect through standard logging unless detailed access logs for specific document revisions are monitored closely.
Mitigation strategies require immediate upgrading to SuiteCRM version 7.15.2 or 8.10.2, where the download logic has been corrected to properly resolve and validate both the revision identifier and its associated parent document before granting file access. For organizations unable to patch immediately due to compatibility constraints with legacy modules, a temporary workaround involves restricting web server-level access to the download.php script for non-administrative users or implementing strict input validation at the application layer to ensure that type=Documents requests are strictly validated against valid documents.id values rather than accepting revision UUIDs directly. Additionally, enabling comprehensive audit logging for file downloads can help detect any ongoing exploitation attempts by monitoring for unusual patterns of access to document revisions from low-privileged accounts.
