ForcedLeak, a critical vulnerability discovered by Noma Labs researchers, has exposed sensitive Customer Relationship Management (CRM) data of organizations using Salesforce Agentforce through an indirect prompt injection attack. This alarming finding highlights the importance of proactive AI security and governance as AI platforms evolve toward greater autonomy.
The ForcedLeak vulnerability was identified in Salesforce Agentforce's Web-to-Lead functionality, which enables users to collect leads and convert them into customers. However, attackers can exploit this feature to inject malicious prompts that execute unauthorized commands when processed by Agentforce. The vulnerability is particularly concerning as it allows attackers to exfiltrate sensitive CRM data, including customer information, lead details, and even credit card numbers.
The attack vector involves an adversary crafting a malicious payload and embedding it within the "Description" field of a Web-to-Lead form. When an employee queries the lead, the AI follows the hidden instructions, the browser requests the image URL, and the attacker's server logs the exfiltrated data. This process is particularly insidious as it disguises itself as legitimate user interactions, making it challenging to detect.
The researchers discovered that Salesforce Agentforce's Content Security Policy (CSP) included an expired whitelisted domain, allowing attackers to exploit this vulnerability. Furthermore, the AI model used in Agentforce lacked the ability to distinguish between legitimate data loaded into its context and malicious instructions that should only be executed from trusted sources.
The disclosure timeline revealed that Noma Labs discovered the vulnerability on July 28, 2025, and published a public report on September 25, 2025. Salesforce responded to the vulnerability within days, implementing Trusted URLs Enforcement for Agentforce & Einstein AI on September 8, 2025. The patch fixes an expired whitelisted domain, which was previously exploited by attackers.
This incident highlights the importance of proactive AI security and governance as AI platforms evolve toward greater autonomy. As Pierluigi Paganini notes in his article, "As AI platforms evolve toward greater autonomy, we can expect vulnerabilities to become more sophisticated." The ForcedLeak vulnerability serves as a strong reminder that even a low-cost discovery can prevent millions in potential breach damages.
