Zenity Labs has disclosed three vulnerabilities in Salesforce Agentforce that could let attackers manipulate AI agents, extract CRM information without a victim clicking a link, and distribute phishing messages. The issues, collectively named SalesBleed, relied on hostile instructions inserted through Salesforce’s public Web-to-Lead forms.
Salesforce worked with Zenity to remediate the reported issues, and the demonstrated exploitation chains no longer function, as first reported by SecurityWeek. Zenity published a technical report and proof-of-concept video showing the attack method.
Public lead forms became a path to AI-agent manipulation
Web-to-Lead lets people submit information through a public form that enters Salesforce lead-management workflows. Zenity’s attack placed malicious instructions into a lead record, creating an indirect prompt injection that waited for an Agentforce request involving leads.
When the agent processed that record, the embedded text could influence its actions. The researchers said this could expose sensitive customer and CRM data with no link click required from the targeted user.
The same access could allow a compromised agent to send phishing material while appearing to act under a trusted agent identity. That creates a difficult detection problem for employees and customers, since a message may come through a system already connected to business records and related tools.
The flaws highlight risks around AI access to business records
Agentforce is designed to work with CRM records and connected tools, giving it access that can make routine sales and support work faster. That also raises the stakes when public, untrusted input can enter the data an agent later reads: a basic lead form can become a route into workflows handling customer information.
Zenity co-founder and CTO Michael Bargury said the findings illustrate how difficult it is to keep AI agents limited to their intended data and actions. The case centers on indirect prompt injection, where hostile commands are stored as ordinary data before an AI system encounters them.
Salesforce and Zenity have not specified when the fixes were deployed, the vulnerability identifiers, or which Agentforce versions were affected. It also remains unclear whether the flaws were exploited before disclosure or how many customers and records were potentially exposed.
