Salesforce Experience Cloud Guest User Misconfiguration Breach 2026
In March 2026, the cybercriminal group ShinyHunters exploited misconfigured guest user profiles in Salesforce's Experience Cloud, leading to unauthorized access to sensitive customer data. By utilizing a modified version of the open-source tool AuraInspector, the attackers scanned public-facing Experience Cloud sites and extracted data without authentication. This breach impacted approximately 400 organizations, including high-profile companies such as Snowflake, Okta, LastPass, Sony, AMD, and Salesforce itself. The compromised data included names, phone numbers, and other CRM information, which were subsequently used for social engineering and voice phishing campaigns. Salesforce confirmed that the issue stemmed from customer-configured settings rather than a vulnerability in its platform.

Misconfigurations, especially in widely used platforms like Salesforce, can lead to significant data breaches, emphasizing the need for organizations to adhere to security best practices and continuously monitor their systems for potential vulnerabilities.
