CVE-2026-22584 is a critical vulnerability classified under CWE-94, indicating improper control over code generation, commonly known as code injection. This vulnerability exists in Salesforce's Uni2TS product versions up to 1.2.0 across multiple operating systems including MacOS, Windows, and Linux. The flaw allows attackers to embed and execute arbitrary code within files that are typically considered non-executable, bypassing normal execution restrictions. This can lead to full compromise of affected systems without requiring any prior authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The vulnerability impacts confidentiality, integrity, and availability severely, with a CVSS score of 9.8. Although no exploits have been reported in the wild yet, the potential for exploitation is high due to the ease of attack and broad scope of affected platforms. The root cause is improper validation or sanitization of code inputs within Uni2TS, allowing malicious payloads to be executed. Salesforce has acknowledged the issue but has not yet released patches, making proactive mitigation critical. This vulnerability poses a significant risk to environments relying on Uni2TS for critical business processes, especially in multi-OS deployments.

For European organizations, the impact of CVE-2026-22584 could be severe. Successful exploitation would allow attackers to execute arbitrary code remotely, potentially leading to data breaches, unauthorized access to sensitive information, disruption of business operations, and complete system compromise. Given that Uni2TS is used across MacOS, Windows, and Linux, the vulnerability affects a wide range of enterprise environments. Confidentiality could be compromised through data exfiltration, integrity could be undermined by unauthorized code execution altering system behavior, and availability could be impacted by denial-of-service conditions or ransomware deployment. The lack of required authentication or user interaction increases the risk of automated exploitation campaigns. European organizations in sectors such as finance, healthcare, and critical infrastructure, which often rely on Salesforce products, could face operational and reputational damage. Additionally, regulatory compliance risks arise due to potential data breaches under GDPR.

Immediate mitigation steps include: 1) Monitoring Salesforce advisories closely for official patches and applying them promptly once available. 2) Implementing strict input validation and sanitization controls around any interfaces interacting with Uni2TS to block malicious payloads. 3) Employing network segmentation and application whitelisting to limit the execution of unauthorized code. 4) Utilizing endpoint detection and response (EDR) solutions to detect anomalous behaviors indicative of code injection attempts. 5) Conducting thorough audits of systems running Uni2TS to identify and isolate vulnerable instances. 6) Restricting file upload and processing functionalities to trusted sources only. 7) Enhancing logging and monitoring to detect early signs of exploitation. 8) Educating security teams about this specific threat to improve incident response readiness. Organizations should also consider temporary compensating controls such as disabling Uni2TS components if feasible until patches are available.
