SuiteCRM Workflow Controller Path Traversal Leading to Code Execution.

CVE advisorySeverity: CRITICAL (CVSS 9.9)

CVE-2026-71550

SuiteCRM is a web-based customer relationship management application typically deployed as an internet-facing or intranet-facing web service. While the vulnerability requires authentication, the platform is commonly accessed via web browsers over a network, making it a likely target for exposure in environments where such business applications are exposed to users.

Horizon Alert

Summary of the vulnerability and why it matters

A vulnerability in SuiteCRM, an open-source customer relationship management software, allows authenticated users with specific roles to execute arbitrary code on the server. This could potentially lead to unauthorized access to sensitive CRM data and configuration secrets, as well as the establishment of persistent access to the system. The issue is present in versions prior to 7.15.2 and 8.10.2, and has been addressed in subsequent releases.

Unauthenticated code execution via CRM workflows.
Business data and system access at risk.
Confirm relevance and ensure systems are updated.

Attack Path

How an attacker could exploit the issue

An attacker with a user account and workflow permissions can exploit this vulnerability by manipulating a specific parameter within the workflow controller. This manipulation allows them to bypass intended security checks and include arbitrary PHP code, ultimately leading to server-side code execution. This could enable them to steal sensitive CRM data, compromise system configurations, and establish persistent backdoors.

Live Threat

Current exploitation, exposure, and threat context

An authenticated user with workflow permissions could execute arbitrary PHP code on the server by exploiting a path-traversal vulnerability in the workflow controller. This could lead to the compromise of sensitive CRM data and configuration secrets.

Operational Fix

Recommended remediation, mitigation, and detection steps

SuiteCRM application owners and infrastructure teams are likely responsible for addressing this vulnerability. The first step is to identify all instances of SuiteCRM, determine their business criticality and external reachability, and confirm the accountable owner for each. This information will inform the remediation plan.

SuiteCRM application owners should own the issue.
Verify workflow controller configuration and access controls.

Frequently asked questions

What is SuiteCRM?

SuiteCRM is an open-source, enterprise-ready application used by organizations to manage customer relationships, sales pipelines, and business data. As a web-based platform, it functions as a central hub where users store sensitive configuration secrets and customer records, requiring a server-side environment to process these workflows and data interactions.

What does CWE-98 mean for CVE-2026-71550?

CWE-98 refers to improper control of file names for include and require statements. In the context of this CVE, the software's workflow controller fails to properly validate the input used to load files. This allows an attacker to manipulate the file path, tricking the server into executing arbitrary PHP files instead of the intended system components.

How is this vulnerability triggered?

An attacker must have an authenticated account with the specific role permissions required to manage workflows. By manipulating the aow_action parameter within the workflow controller, they can trigger the insecure file inclusion. Notably, this flaw cannot be exploited by unauthenticated visitors; it specifically requires authorized access to the workflow features to initiate the path traversal.

Is my SuiteCRM instance relevant for this threat?

If you use SuiteCRM, your system is relevant because Halo Surface Signal identifies it as a likely target for network-based access. Since the application is typically deployed as a web service—either internet-facing or within an intranet—its accessibility over a network increases the potential for an authenticated attacker to reach the vulnerable workflow controller.

What is the first step to address CVE-2026-71550?

You should immediately identify all SuiteCRM instances within your environment and check their current version numbers. If you are running a version earlier than 7.15.2 or 8.10.2, you must prioritize upgrading to these patched releases or newer to eliminate the vulnerability and protect your CRM data from unauthorized code execution.
