CVE-2025-64321 identifies a vulnerability categorized under CWE-1427, which concerns improper neutralization of input used for LLM prompting within the Salesforce Agentforce Vibes Extension. This extension, used to enhance Salesforce CRM capabilities, processes input data that is incorporated into prompts for large language models. The vulnerability arises because input is not adequately sanitized or validated before being used in these prompts, allowing an attacker to inject malicious content. This injection can manipulate writable configuration files associated with the extension, potentially altering system behavior or enabling further attacks. The affected versions are all prior to 3.2.0, with no patch links currently available. The vulnerability does not require prior authentication or user interaction, increasing its risk profile. While no exploits have been observed in the wild, the flaw could be leveraged to compromise the integrity of Salesforce configurations, disrupt service availability, or facilitate privilege escalation within affected environments. The lack of a CVSS score necessitates an independent severity assessment based on impact and exploitability factors.

For European organizations, the impact of this vulnerability could be significant, particularly for enterprises heavily reliant on Salesforce CRM and its extensions for customer management, sales, and service operations. Manipulation of writable configuration files could lead to unauthorized changes in system behavior, potentially causing data integrity issues, service disruptions, or enabling further exploitation such as privilege escalation or lateral movement within corporate networks. Industries such as finance, telecommunications, and manufacturing, which often use Salesforce extensively, may experience operational downtime or data breaches if exploited. The vulnerability could also undermine trust in CRM data accuracy and availability, affecting compliance with data protection regulations like GDPR. Since the vulnerability does not require authentication or user interaction, attackers could exploit it remotely if they gain access to the extension interface, increasing the threat surface for European businesses.

To mitigate this vulnerability, European organizations should prioritize upgrading the Salesforce Agentforce Vibes Extension to version 3.2.0 or later once it becomes available, as this version is expected to address the input neutralization issue. Until a patch is released, organizations should implement strict input validation and sanitization controls on any data fed into LLM prompts within the extension. Access to writable configuration files should be tightly controlled using role-based access controls (RBAC) and monitored for unauthorized changes. Employing application-layer firewalls or endpoint detection systems to detect anomalous behavior related to configuration file modifications can provide additional defense. Regular audits of configuration files and logs should be conducted to identify suspicious activities early. Additionally, organizations should review their Salesforce environment for unnecessary exposure of the extension interfaces and restrict network access to trusted users and systems only.
