CVE-2026-69140 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, GetLatestRevision.php interpolates get_latest_for_id directly into an SQL UPDATE statement. Although securexss() normally entity-encodes quotes, an input prefixed with an XSS payload makes AntiXSS select a processed string instead of the encoded backup, allowing a literal quote to reach the query. A low-privileged user with Documents module access can disclose database data and mass-update linked_documents records, while stacked statements and arbitrary DROP or INSERT operations are not supported by this vector. This issue is fixed in versions 7.15.2 and 8.10.2.

SuiteCRM serves as a prominent open-source Customer Relationship Management platform designed for enterprise environments, yet it has historically been susceptible to injection-based vulnerabilities that compromise data integrity. A critical flaw exists within the GetLatestRevision.php component in versions prior to 7.15.2 and 8.10.2, where the application fails to properly sanitize user-supplied input before incorporating it into SQL UPDATE statements. The vulnerability stems from a logic error in the security filtering mechanism known as AntiXSS. Under normal circumstances, the securexss function is responsible for entity-encoding special characters such as quotes to prevent injection attacks. However, this safeguard can be bypassed through a specific technique involving input prefixed with an XSS payload. When such maliciously crafted input is processed, the AntiXSS library incorrectly selects a pre-processed string variant rather than applying the necessary HTML entity encoding to the backup value. This oversight results in literal quote characters being passed directly into the database query without proper escaping or parameterization.
The technical nature of this flaw aligns with CWE-89 Improper Neutralization of Special Elements used in an SQL Command, commonly referred to as SQL Injection. By manipulating the input string, a low-privileged user who possesses access to the Documents module can inject arbitrary commands into the UPDATE statement executed by GetLatestRevision.php. This capability allows attackers to modify database records beyond their intended scope. Specifically, the vulnerability enables mass updates to linked_documents records, which are critical for maintaining relationships between files and other entities within the CRM system. While this vector does not support stacked statements or operations such as arbitrary DROP or INSERT commands due to limitations in how the query is constructed, it still poses a severe risk to data integrity. An attacker can alter existing record associations, potentially leading to unauthorized access patterns or disruption of document management workflows.
The operational impact of this vulnerability extends beyond simple data modification. Because SuiteCRM relies on accurate linkage between documents and their associated records for proper functionality, corrupting these links can degrade system usability and trust in the stored information. Furthermore, while direct database disclosure is limited by the nature of an UPDATE statement rather than a SELECT query, the ability to mass-update linked_documents could be leveraged in conjunction with other vulnerabilities or logic flaws to escalate privileges or exfiltrate data indirectly. The vulnerability highlights the dangers of relying on complex security libraries that may have edge-case failures when handling specific input patterns. It underscores the necessity for defense-in-depth strategies where application-level filtering is supplemented by strict parameterized queries and least-privilege database access controls.
To mitigate this risk, organizations running SuiteCRM must immediately upgrade to version 7.15.2 or 8.10.2, which contain patches addressing the input validation logic in GetLatestRevision.php. Until an upgrade can be performed, administrators should restrict access to the Documents module and any related API endpoints that trigger the vulnerable code path. Implementing a Web Application Firewall with rules tuned to detect SQL injection patterns involving quote manipulation may provide temporary relief, though it is not a substitute for patching. Long-term remediation involves adopting secure coding practices such as using prepared statements exclusively for all database interactions, thereby eliminating the possibility of input interpolation into query structures regardless of how filters behave. This approach aligns with ATT&CK technique T1059 Command and Scripting Interpreter if an attacker were to attempt further exploitation via stacked queries in other contexts, although this specific vector is limited to update operations. Ensuring that security libraries are correctly configured and tested against edge cases remains a critical component of maintaining the integrity of enterprise CRM deployments.
