CVE-2026-29108 in SuiteCRM
Summary
by MITRE • 03/20/2026
SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to versions 8.9.3, an authenticated API endpoint allows any user to retrieve detailed information about any other user, including their password hash, username, and MFA configuration. As any authenticated user can query this endpoint, it's possible to retrieve and potentially crack the passwords of administrative users. Version 8.9.3 patches the issue.

The vulnerability identified as CVE-2026-29108 affects SuiteCRM versions prior to 8.9.3, representing a critical authorization flaw that undermines the fundamental security principles of user access control within the application. This issue resides in the API endpoint design where proper access controls have been omitted, allowing any authenticated user to query and retrieve comprehensive user account information regardless of their privileges or role within the system. The flaw manifests as an insufficient authorization check that permits unauthorized information disclosure, creating a pathway for privilege escalation and credential compromise.
The technical implementation of this vulnerability stems from a lack of proper access control validation within the API endpoint responsible for user information retrieval. The affected endpoint does not perform adequate user role verification or permission checks before returning sensitive user data including password hashes, usernames, and multi-factor authentication configurations. This design flaw directly maps to CWE-285, which addresses insufficient authorization issues in software systems, where applications fail to properly enforce access controls for protected resources. The vulnerability enables what is commonly referred to as a "user enumeration" attack pattern, where malicious actors can systematically gather information about other users within the system.
From an operational impact perspective, this vulnerability poses significant risks to SuiteCRM deployments as it allows any authenticated user to potentially compromise administrative accounts through credential harvesting and subsequent password cracking attempts. The exposure of password hashes provides attackers with the means to conduct offline password attacks, while the inclusion of MFA configuration details eliminates potential security layers that would otherwise protect against unauthorized access. This vulnerability directly aligns with ATT&CK technique T1078 which covers valid accounts and credential access, as it enables attackers to leverage legitimate user accounts to escalate privileges and gain deeper system access. The impact extends beyond simple information disclosure as it creates opportunities for privilege escalation, account takeover, and potential lateral movement within the network.
Organizations utilizing SuiteCRM versions prior to 8.9.3 should immediately implement comprehensive mitigation strategies to address this vulnerability. The primary and most effective mitigation involves upgrading to SuiteCRM version 8.9.3 or later, which includes the necessary access control patches. Additionally, administrators should conduct thorough access control reviews and implement network segmentation to limit API endpoint exposure. Security monitoring should be enhanced to detect unusual API access patterns, particularly those involving user enumeration requests. The vulnerability also highlights the importance of regular security assessments and vulnerability scanning to identify similar authorization flaws within application components. Organizations should also consider implementing additional authentication controls such as rate limiting and IP-based access restrictions for API endpoints to reduce the attack surface. The remediation process should include comprehensive user access reviews to ensure that only authorized personnel have access to sensitive system functions, and that proper principle of least privilege is enforced throughout the application.
