    Summary
    Successful exploitation of this vulnerability allows an authenticated attacker to escalate privileges and access spaces outside their assigned partition, within the same Salto ProAccess Space installation or system. Exploitation requires valid authenticated operator credentials and the partition feature to be enabled; installations without partitioning are not affected. The following versions of SALTO ProAccess Space are affected:

    ProAccess Space <6.13 (CVE-2026-11889)

    Remediations
    MitigationUsers of SALTO ProAccess using the tenancy feature should upgrade to version 6.13.
    Vendor fixTo further enhance security after applying the update: 1. Operate ProAccess Space on a protected internal network and avoid exposing it directly to the Internet. 2. Restrict operator-level accounts to the minimum required and apply least-privilege principles. 3. If feasible, disable the partitioning feature and operate under a single partition. 4. When strong tenant separation is required, consider running separate Space instances (isolated environments) rather than relying solely on logical partitioning.

    Recommended Practices
    CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
    CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices
    on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
    CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
    Strategies.
    Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
    No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time.
