CVE-2026-4802: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Red Hat Red Hat Enterprise Linux 10
CVE-2026-4802 is a high-severity vulnerability in Cockpit on Red Hat Enterprise Linux 10 that allows remote attackers to execute arbitrary OS commands. The flaw arises from improper neutralization of special elements in user-controlled parameters within the system logs UI, enabling injection of shell metacharacters and command substitutions. Successful exploitation can lead to complete system compromise. No official patch or remediation guidance is currently confirmed from the vendor advisory.
AI Analysis
Technical Summary
This vulnerability in Red Hat Enterprise Linux 10's Cockpit interface involves improper sanitization of user-supplied parameters in the system logs UI. Attackers can craft links containing shell metacharacters and command substitutions that the system executes, resulting in arbitrary command execution on the host. The CVSS 3.1 score is 8.0, reflecting high impact on confidentiality, integrity, and availability. The vendor advisory does not currently specify a remediation level or patch availability.
Potential Impact
Exploitation allows remote attackers with limited privileges to execute arbitrary shell commands on the affected system, potentially leading to full system compromise. This impacts confidentiality, integrity, and availability of the host running Red Hat Enterprise Linux 10 with Cockpit. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-4802 for current remediation guidance. Until an official fix is available, restrict access to the Cockpit system logs UI to trusted users only and monitor for suspicious activity related to crafted links. Follow vendor updates closely for patch releases.
