CVE-2026-2832 is classified under CWE-200 (Information Exposure) and affects HP Inc's Samsung MultiXpress multifunction printers, specifically models SL-X7600LXR, SL-X7500LXR, and SL-X7400LXR. The vulnerability arises from insufficient authorization controls on certain device APIs, which allow unauthenticated remote attackers to retrieve sensitive information such as address book entries and device configuration details. These details can include contact information stored on the device and potentially other configuration parameters that could aid further attacks or reconnaissance. The attack vector is remote and requires no privileges or user interaction, making it relatively easy to exploit in environments where the printer management interfaces are exposed or accessible within a network. The CVSS 4.0 vector (AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N) indicates the attack is network-based (adjacent network), with low complexity and no authentication required, but the impact on confidentiality is limited (partial information disclosure). No integrity or availability impacts are noted. Currently, there are no known exploits in the wild, and no patches have been released, which suggests the vulnerability is newly disclosed. The lack of patch availability necessitates interim mitigations to reduce exposure. This vulnerability is significant because multifunction printers are often integrated into enterprise networks and may contain sensitive contact and configuration data that could be leveraged for social engineering or further network attacks.

The primary impact of CVE-2026-2832 is unauthorized disclosure of sensitive information stored on affected Samsung MultiXpress printers. This includes address book entries and device configuration data, which could reveal internal contact details, network configurations, or operational parameters. Such information leakage can facilitate targeted phishing, social engineering, or lateral movement within an organization’s network. Although the vulnerability does not directly compromise device integrity or availability, the exposure of sensitive data can undermine organizational confidentiality and privacy policies. Enterprises with large deployments of these printer models, especially in sectors handling sensitive or regulated data (e.g., government, finance, healthcare), face increased risk of information leakage. The medium CVSS score reflects the moderate severity due to ease of exploitation but limited scope of impact. However, if combined with other vulnerabilities or insider threats, this information disclosure could contribute to more severe attacks. The absence of known exploits currently limits immediate widespread impact, but the vulnerability should be addressed proactively to prevent future exploitation.

To mitigate CVE-2026-2832, organizations should first restrict network access to the affected printer management interfaces by implementing network segmentation and firewall rules that limit access to trusted administrators only. Disable or restrict API access where possible, especially from untrusted or public networks. Employ strong network access controls such as VPNs or zero-trust network access for remote printer management. Monitor network traffic for unusual access patterns to printer APIs. Regularly audit printer configurations and address book contents to minimize sensitive data stored on the device. Since no patches are currently available, consider temporarily disabling unused services or APIs on the printers. Engage with HP Inc for updates on patches or firmware upgrades addressing this vulnerability. Additionally, educate IT staff about the risks of information disclosure from networked devices and incorporate printer security into broader endpoint security policies. Finally, maintain an inventory of affected devices and track any vendor advisories for timely remediation.
