CVE-2025-43700: Salesforce OmniStudio Information Disclosure

CVE-2025-43700 Overview

CVE-2025-43700 is an Improper Preservation of Permissions vulnerability (CWE-281) affecting Salesforce OmniStudio, specifically the FlexCards component. This vulnerability allows unauthorized exposure of encrypted data due to improper permission handling within the application framework.

The flaw exists in versions of OmniStudio prior to the Spring 2025 release. Due to the improper preservation of permissions, attackers can potentially access encrypted data without proper authorization, posing significant risks to organizations relying on Salesforce OmniStudio for their business processes.

Critical Impact
Unauthorized exposure of encrypted data through improper permission preservation in Salesforce OmniStudio FlexCards, potentially compromising confidential information stored within the platform.

Affected Products

Salesforce OmniStudio (FlexCards) - versions before Spring 2025
OmniStudio installations not updated to Spring 2025 release
Organizations using FlexCards components with sensitive encrypted data

Technical Details for CVE-2025-43700

Vulnerability Analysis

This vulnerability stems from improper preservation of permissions (CWE-281) within the Salesforce OmniStudio FlexCards component. The flaw allows network-based attackers to bypass permission checks and gain unauthorized access to encrypted data. The vulnerability requires no authentication or user interaction to exploit, making it particularly dangerous in exposed environments.

The attack can be executed remotely over the network, and successful exploitation results in unauthorized disclosure of confidential information. While the vulnerability does not allow modification or deletion of data (integrity and availability remain unaffected), the potential for sensitive data exposure represents a significant security concern for organizations using OmniStudio.

Root Cause

The root cause of CVE-2025-43700 lies in the improper preservation of permissions within the FlexCards component of OmniStudio. When handling encrypted data, the application fails to properly maintain and enforce permission boundaries, allowing unauthorized access to protected information. This permission handling flaw enables attackers to circumvent access controls that should otherwise protect encrypted data from unauthorized disclosure.

Attack Vector

The vulnerability is exploitable via network-based attacks without requiring authentication or user interaction. An attacker can remotely target affected OmniStudio installations to access encrypted data that should be protected by permission controls.

The attack flow typically involves:

Identifying a vulnerable OmniStudio installation with FlexCards components
Crafting requests that exploit the permission preservation flaw
Accessing encrypted data without proper authorization
Extracting confidential information that bypasses intended access controls

Due to the nature of this vulnerability, no code examples are provided. Organizations should refer to the Salesforce Support Article for detailed technical information about the vulnerability and its exploitation vectors.

Detection Methods for CVE-2025-43700

Indicators of Compromise

Unusual access patterns to FlexCards components from unauthorized users or IP addresses
Unexpected data retrieval requests targeting encrypted fields within OmniStudio
Anomalous API calls to OmniStudio endpoints that bypass normal authentication flows
Log entries indicating permission check failures followed by successful data access

Detection Strategies

Monitor OmniStudio access logs for unauthorized attempts to access encrypted data
Implement alerting for anomalous patterns in FlexCards component usage
Review audit trails for permission-related anomalies in data access operations
Deploy network-level monitoring for unusual traffic patterns to OmniStudio endpoints

Monitoring Recommendations

Enable comprehensive logging for all OmniStudio FlexCards operations
Configure alerts for data access attempts from unauthenticated or low-privilege contexts
Implement real-time monitoring of encrypted data access patterns
Establish baseline metrics for normal FlexCards usage to identify deviations

How to Mitigate CVE-2025-43700

Immediate Actions Required

Upgrade Salesforce OmniStudio to Spring 2025 or later release immediately
Audit existing FlexCards configurations for sensitive encrypted data exposure
Review access logs for any signs of exploitation prior to patching
Implement additional network-level access controls while patching is in progress

Patch Information

Salesforce has addressed this vulnerability in the Spring 2025 release of OmniStudio. Organizations should upgrade to the Spring 2025 version or later to remediate CVE-2025-43700. Detailed patching instructions and release notes are available through the Salesforce Support Article.

Workarounds

Restrict network access to OmniStudio FlexCards components to trusted IP ranges
Implement additional authentication layers in front of OmniStudio endpoints
Temporarily disable FlexCards features that handle sensitive encrypted data until patching is complete
Review and tighten permission configurations for all OmniStudio components as an interim measure
