CVE-2026-69134 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, the REST v4 JSON handler reads the pre-filter RAW_REQUEST value and relationship write helpers interpolate supplied field values into INSERT and UPDATE statements. The affected flow begins at $GLOBALS['RAW_REQUEST'] and uses set_relationship, SugarRelationship::addRow(), SugarRelationship::updateRow(), and contact_role to carry attacker-controlled data or authorization state into the security-sensitive operation. An authenticated user can inject SQL through relationship fields to read or alter database data and may reach file-write consequences when the database account has elevated privileges. 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 SQL injection vulnerability within its REST API implementation prior to version 7.15.2 and 8.10.2. The flaw resides in the handling of relationship data through the v4 JSON handler, specifically involving the interaction between pre-filtered raw request values and database write operations. When an authenticated user interacts with the system via the set_relationship endpoint, the application processes input fields that are intended to define relationships between entities such as contacts and roles. Instead of properly sanitizing or parameterizing these inputs before they reach the database layer, the software interpolates supplied field values directly into INSERT and UPDATE SQL statements through methods like SugarRelationship::addRow() and SugarRelationship::updateRow(). This architectural oversight allows an attacker who has valid authentication credentials to inject arbitrary SQL commands by manipulating relationship fields.
The technical mechanism of this vulnerability relies on the improper handling of data flowing from $GLOBALS['RAW_REQUEST'] into security-sensitive operations involving contact_role relationships. Because the input is not adequately validated or escaped before being concatenated into database queries, it falls under the category of CWE-89 Improper Neutralization of Special Elements used in an SQL Command. This type of injection enables attackers to bypass intended access controls and manipulate backend data structures. The severity of this issue is compounded by the potential for privilege escalation if the database account running SuiteCRM possesses elevated privileges. In such scenarios, successful exploitation can lead not only to unauthorized reading or alteration of sensitive customer data but also to file-write consequences on the underlying server operating system, effectively allowing remote code execution through out-of-band techniques common in advanced SQL injection attacks.
From an operational perspective, this vulnerability poses a significant risk to organizations relying on SuiteCRM for managing critical business relationships and client information. An authenticated attacker can exploit this flaw to exfiltrate confidential data, modify records to disrupt business operations, or potentially gain persistent access by modifying application configurations or injecting malicious scripts if the database permissions are misconfigured. The presence of such a vulnerability undermines the integrity and confidentiality guarantees expected from enterprise-grade CRM software. It highlights the dangers of legacy code patterns where dynamic query construction is used without modern parameterization standards, leaving systems exposed to well-known exploitation techniques that have been prevalent in web application security for decades.
To mitigate this risk, organizations must immediately upgrade SuiteCRM to version 7.15.2 or later, which includes patches addressing the improper input handling in the relationship write helpers and REST JSON handler. For environments where immediate patching is not feasible due to compatibility constraints, implementing a Web Application Firewall with rules specifically tuned to detect SQL injection patterns within API request bodies can provide temporary protection. Additionally, enforcing strict database least-privilege principles ensures that even if an injection occurs, the attacker cannot leverage high-level permissions for file system access or administrative control. Regular security audits and code reviews focusing on data flow from user inputs to database queries are essential preventive measures against such vulnerabilities aligned with ATT&CK techniques related to SQL Injection and Data Exfiltration via Application Layer Protocols.
