Noma Security Reveals Critical Salesforce Agentforce Flaw: ForcedLeak Highlights AI Agent Risks

Overview: A critical flaw in Salesforce Agentforce

Israeli cybersecurity firm Noma Security disclosed a severe security vulnerability in Salesforce’s AI agent platform, Agentforce. Dubbed ForcedLeak, the flaw earned a CVSS score of 9.4 and was promptly fixed by Salesforce after the report. The incident underscores a growing class of risks tied to autonomous AI agents, where subtle manipulations can trigger unintended, data-leaking actions without user intervention.

How the exploit worked: Indirect Prompt Injection

The vulnerability was exploited through a technique known as Indirect Prompt Injection. An attacker submitted a normal-looking lead form but embedded a covert instruction that compelled the AI agent to fetch an external image resource. In practice, the agent, while handling a lead, constructed a web request that included fields and data from the company’s CRM — such as names, contact details, and lead summaries — inside the request payload or in a URL sent to an external server. To ensure the request appeared legitimate, the attacker purchased an old, previously Salesforce-authenticated domain for a nominal cost (around $5). This legitimacy trick made the agent treat the request as a routine part of lead processing rather than a malicious action.

When the AI agent was asked to review the lead, it automatically executed the embedded instructions and loaded the external resource. The data was transmitted to the attacker-controlled server without any human confirmation or intervention.

What data could have been exposed

The risk wasn’t Salesforce’s own secrets; it was the customer data stored in Salesforce CRM systems. Exposed information could include client contact details, lead inquiries, marketing and sales notes, and internal deal statuses. In short, a company using online forms to capture leads could inadvertently leak sensitive customer data if an autonomous agent is manipulated to exfiltrate information via external calls.

Why this matters: AI agents and new attack surfaces

ForcedLeak illustrates a broader shift in security threats: the primary risk is not merely click-based user actions but the manipulation of autonomous AI agents themselves. Traditional monitoring and controls often fail to detect or prevent hidden prompts or extrinsic data-loading behaviors performed by agents operating with broad permissions. This incident demonstrates why organizations must rethink access controls, data minimization, and watchdog mechanisms in AI-driven workflows.

Salesforce response and industry implications

Salesforce released a patch after Noma Security’s disclosure, addressing the vulnerability and hardening the agent’s handling of external prompts. For customers, the episode emphasizes several best practices: implement strict domain allowlists so agents can only fetch resources from trusted sources; enforce stricter validation of prompts and inputs; minimize data exposed to AI agents; and monitor agent activity for anomalous external requests. Beyond Salesforce, the event signals a need for industry-wide standards around AI agent governance, including risk scoring for prompts, automatic detection of indirect data exfiltration attempts, and improved telemetry for autonomous actions.

Noma Security: a forward-looking player in AI risk management

Founded in 2023 by Israeli security experts, Niv Braun and Alon Tron, Noma Security has positioned itself at the forefront of AI risk discovery and governance. With significant fundraising and a focus on AI risk visibility, the firm emphasizes that embracing intelligent tooling in business operations must go hand in hand with robust security controls and compliance. The ForcedLeak disclosure aligns with a broader industry push to secure AI-assisted sales, marketing, and customer relationship management ecosystems.

Conclusion: preparing for AI-driven workflows

The ForcedLeak case is a warning that AI agents can become vectors for data leakage if their prompts and external requests are not properly contained. Organizations should adopt a zero-trust approach to AI integrations, enforce strict data access policies, and invest in monitoring tools capable of detecting indirect prompt injections and unusual external data calls. As AI-powered automation becomes more prevalent in CRM and customer-facing processes, proactive governance and secure-by-design practices will be essential to maintaining confidentiality and trust.
