CVE-2025-54784 Overview
SuiteCRM is an open-source enterprise Customer Relationship Management (CRM) application maintained by SalesAgility. CVE-2025-54784 is a stored Cross-Site Scripting (XSS) vulnerability [CWE-79] in the email viewer component of SuiteCRM versions 7.14.0 through 7.14.6. An unauthenticated external attacker can send a crafted email to an inbox monitored by a SuiteCRM instance. When a logged-in user opens the message in the email viewer, the embedded payload executes in the victim's browser session. SalesAgility fixed the flaw in SuiteCRM 7.14.7.
Critical Impact
An attacker can execute arbitrary JavaScript in the context of any user who views a malicious email, enabling data exfiltration, session hijacking, and full instance takeover when an administrator triggers the payload.
Affected Products
- SalesAgility SuiteCRM 7.14.0
- SalesAgility SuiteCRM versions 7.14.1 through 7.14.6

Technical Details for CVE-2025-54784
Vulnerability Analysis
The flaw resides in the SuiteCRM email viewer, which renders inbound email content in the authenticated user's browser. The application fails to properly sanitize HTML and JavaScript content contained in incoming messages before rendering. When the user opens the email, the browser parses and executes the attacker-controlled markup within the SuiteCRM origin. This gives the payload full access to the user's active session, CSRF tokens, and DOM. If the viewing user holds administrative privileges, the attacker inherits those privileges and can pivot to configuration changes, user creation, or code execution paths available to admins.
Root Cause
The root cause is missing or insufficient output encoding of untrusted email body content in the email viewer. HTML entities, event handler attributes, and script constructs delivered inside a message are passed to the DOM without neutralization, violating the guidance associated with [CWE-79].
Attack Vector
Exploitation requires only that the attacker know or guess an email address monitored by the target SuiteCRM instance. The attacker sends a message containing the malicious payload to that inbox. No authentication is required on the attacker side. The victim triggers the payload by viewing the message in SuiteCRM, satisfying the passive user interaction requirement. Because SuiteCRM ingests messages automatically, the payload persists in the mail store, giving this vulnerability stored-XSS characteristics.
No public proof-of-concept exploit code is available for this issue. See the GitHub Security Advisory GHSA-vg8q-xcq5-mh3p for vendor technical details.
Detection Methods for CVE-2025-54784
Indicators of Compromise
- Inbound email messages containing <script> tags, on* event handlers, javascript: URIs, or obfuscated HTML in the body or subject fields.
- Unexpected outbound HTTP requests from user browsers to attacker-controlled domains immediately after opening a SuiteCRM email.
- Creation of new administrative users, API tokens, or role changes in SuiteCRM without a corresponding change-management record.
Detection Strategies
- Inspect SuiteCRM database tables that store email bodies for HTML patterns associated with XSS payloads, focusing on messages received before upgrade to 7.14.7.
- Deploy a Content Security Policy (CSP) in report-only mode in front of SuiteCRM and review violation reports for inline script execution originating from the email viewer.
- Correlate web server access logs with mail ingestion timestamps to identify session cookie theft attempts that follow shortly after a user opens the mail module.
Monitoring Recommendations
- Alert on administrator account activity that originates from unusual IP addresses or user agents shortly after email viewing sessions.
- Monitor SuiteCRM audit logs for privilege changes, role assignments, and configuration edits and require secondary review for admin-level changes.
- Add signature or heuristic scanning at the mail gateway to strip or quarantine messages containing active HTML script content directed at CRM mailboxes.
How to Mitigate CVE-2025-54784
Immediate Actions Required
- Upgrade all SuiteCRM instances running 7.14.0 through 7.14.6 to version 7.14.7 or later.
- Force-logout all active SuiteCRM sessions after upgrade and require password rotation for administrative accounts.
- Audit user, role, and integration configuration for unauthorized changes introduced during the exposure window.
Patch Information
SalesAgility released the fix in SuiteCRM 7.14.7. Refer to the SuiteCRM 7.14.7 release notes and the GitHub Security Advisory for upgrade procedures and validation steps.
Workarounds
- Restrict which mailboxes SuiteCRM ingests and disable automatic inbound email import for high-privilege accounts until the patch is applied.
- Deploy a strict Content Security Policy that blocks inline scripts and untrusted event handlers on the SuiteCRM origin.
- Instruct administrators to view email content in a plain-text or external client rather than through the SuiteCRM email viewer until upgrade is complete.
