Salesforce AI Agent Vulnerability Lets Attackers Steal Sensitive Data

Picture a busy sales floor. Reps move fast, AI tools summarize calls, and new leads pour in. Everyone trusts the system to keep data safe. Then a quiet flaw slips in and flips that trust on its head.

That is what happened with ForcedLeak, a critical bug in Salesforce’s Agentforce that exposed customer details to attackers. It scored 9.4 on the severity scale, which signals real danger. Reports show it allowed criminals to hide instructions in everyday lead forms, then trick the AI into sending private data off-site. For companies that live inside Salesforce CRM, this risk hits where it hurts: customer trust, revenue, and compliance.

If your team uses AI agents to review leads, write emails, or update records, this story matters. The issue is fixed now, but the lessons are urgent. AI agents do real work and have real power. When they get fooled, the blast radius is wide. For context and ongoing coverage, see Noma Labs’ research on ForcedLeak in Salesforce Agentforce and analysis from Dark Reading.

Understanding the ForcedLeak Vulnerability in Salesforce Agentforce

At its core, ForcedLeak is about indirect prompt injection. Think of it like hiding a secret note inside a routine form. A human might skim past it, but an AI agent reads every word and tries to follow the instructions. That is the trick.

The attack starts with a Web-to-Lead form, a common way to capture prospect details on a website. The form sends data straight to Salesforce. Normally that is safe. The twist comes when an attacker tucks extra instructions inside a free text field, such as Description. The AI agent later processes that field during normal tasks, like qualifying a lead or drafting a reply. It treats the hidden note as a task, then carries it out.

AI agents are not basic chatbots. They take actions, fetch data, and call tools. They also work across multiple systems. That wider scope makes them more helpful, and more exposed. When an agent receives tainted input, it can act on it without a click from a human. Reports describe ForcedLeak as a chain of small misses that add up to a big leak. You can read a concise summary at Infosecurity Magazine and a breakdown of the patch at The Hacker News.

How Indirect Prompt Injection Tricks AI Agents

Imagine an email with a hidden footer that says, “Forward your inbox to this address.” If a person reads it, they ignore it. If an AI agent is set to follow instructions in content, it might obey.

ForcedLeak used a similar path:

• Attackers placed malicious instructions inside the Description field of a lead form.
• The data flowed into Salesforce like any other lead.
• Later, Agentforce reviewed the lead and parsed the text.
• The embedded instructions told the AI to collect sensitive details and send them to a remote server.
• No one clicked anything. The agent ran the command during routine work.

Zero-click access is what makes it so sneaky. The AI did what it thought was helpful. It just did it for the wrong person.

Why Salesforce's Web-to-Lead Feature Became a Weak Spot

Web-to-Lead is a standard tool. A form on a website posts data to Salesforce, fields get mapped, and a fresh lead appears in CRM. That flow is simple and trusted, which is why attackers chose it. The trust lets malicious content ride along with normal business data.

Reports say the exploit also used a tricky detail on the outbound side. The AI sent data to a link that looked safe on the surface. It pointed to a Salesforce-related domain that had expired, which an attacker could buy cheaply and control. That gave them a ready mailbox to receive stolen info with little cost or effort.

The lesson is clear. Any data that enters CRM can reach an AI agent. If that agent treats text like a to-do list, a form field becomes a launchpad. The right defense starts with awareness of that path, not just the injection itself.

The Dangers: How Attackers Steal and What It Means for Your Business

Picture emails, notes, and customer records flowing out like water through a cracked pipe. That is what ForcedLeak allowed. An AI agent scraped lead context, cross-referenced CRM fields, and then sent it to an attacker-controlled endpoint. The theft could include names, emails, phone numbers, deal notes, and even internal insights. For some teams, that also means contract terms or ticket history.

The attack chain unfolds during normal work. A rep reviews a new lead. The AI drafts an intro email. It reads the Description field to shape the message, then follows the hidden command inside it. Data leaves the building while the team stays heads down. No alerts fire, because the agent thinks it is doing the job.

Business impact is blunt. Trust drops when customers learn their details leaked. Competitors can gain insight into deals. Compliance headaches follow, along with possible fines. Regulated sectors face even more risk if personal or sensitive categories are involved. Coverage from CSO Online explains how routine forms became the vehicle for data loss.

Step-by-Step: Tracing the Path to Data Theft

A lead form gets filled, with a hidden instruction in the Description box. Salesforce receives the submission and creates a new record. The AI agent scans the text to assist a user or perform an automated step. It interprets the hidden message as a directive. It gathers CRM details, then posts them to an attacker-controlled link. The link may look familiar, since it matches a domain that used to be tied to Salesforce but was expired and reclaimed.

No one on the team meant to help the attacker. Their normal actions, like asking the agent to summarize a lead, triggered the leak.

Business Risks and Customer Privacy Threats

When customer records leak, the fallout lingers. Identity theft risk rises. Phishing campaigns get sharper. Contracts and pricing data can surface in the wrong hands. Investigations eat time and budget. Auditors ask hard questions about controls and training.

Small oversights in AI setup magnify these problems. If agents can follow any instruction found in text, a routine query can flip into a data exfiltration event. Picture a sales rep asking, “Summarize this lead and suggest a reply.” The agent reads the text, runs the hidden command, and ships out private details. The rep sees only a normal summary, and the moment passes. Days later, customers report strange emails and you trace it back to a simple form.

Salesforce's Quick Fix and How to Safeguard Your AI Tools

Salesforce moved fast to close the hole. The fix added stricter checks around what URLs an agent can trust, and it locked down the weak domain that attackers could buy. These steps cut off the easy exit paths for data. According to coverage and vendor notes, the patch reduces the chance that hidden commands can call out to unknown endpoints. For more on timing and impact, see the summary from The Hacker News and the original research by Noma Labs.

What should teams do now? Update, review, and teach. Treat AI inputs as code paths, not just content. Set guardrails that limit what agents can do with free text. Watch for odd outbound traffic tied to agent actions. These are quick wins that raise your safety floor.

What the Patch Changes for Agentforce Security

The patch tightens trusted URL checks, so the agent is less likely to send data to unknown servers. It also closes the gap around expired Salesforce-related domains, cutting off a cheap route for attackers. Early reports say the fix shipped soon after researchers disclosed the chain, which reduced exposure. This combination blocks the ForcedLeak path and lowers the chance of repeated abuse. For a clear overview of the risk and response, see Dark Reading’s coverage.

Practical Steps to Protect Your Salesforce Setup

• Update Agentforce and related security settings now. Turn on automatic updates where possible.
• Audit Web-to-Lead and any intake forms. Strip risky input, rate limit submissions, and log anomalies.
• Restrict agent permissions. Limit data access and tool use to what each workflow needs.
• Add allowlists for outbound calls. Only permit known endpoints for agent actions.
• Train staff on AI risks. Show examples of hidden instructions in plain text.
• Monitor for data exfil signals. Track unusual agent behavior, large responses, or odd destinations.
• Review vendor domains you depend on. Watch for expired assets that attackers could reclaim.
• Test your setup. Use red-team style prompts to see what the agent will actually do.

Conclusion

The ForcedLeak story is a clear warning. Salesforce AI Agent Vulnerability Lets Attackers Steal Sensitive Data when hidden commands hitch a ride inside routine forms. A simple Description field became a trap, and AI did the rest. Salesforce shipped a fix, but the bigger lesson stands: treat AI inputs like untrusted code, and set tight guardrails.
