CVE-2026-55748: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in OpenStack Horizon
CVE-2026-55748 is an OS command injection vulnerability in OpenStack Horizon versions 8.0.0, 25.4.0, and 25.6.0. It arises from improper neutralization of special shell metacharacters in project names used when generating scripts for OpenStack RC file downloading. This vulnerability may allow an attacker with certain privileges to execute arbitrary commands. The issue is considered by some as a security hardening opportunity rather than a straightforward vulnerability. The CVSS score is 6.0, indicating medium severity.
AI Analysis
Technical Summary
OpenStack Horizon before version 25.7.4 generates scripts for downloading OpenStack RC files that incorporate project names without properly neutralizing shell metacharacters. This improper neutralization (CWE-78) can lead to OS command injection if a crafted project name is used. The vulnerability affects specific versions including 8.0.0, 25.4.0, and 25.6.0. No official patch or remediation level has been published yet. The CVSS 3.1 vector indicates network attack vector, high attack complexity, requiring privileges and user interaction, with high confidentiality and integrity impact and low availability impact.
Potential Impact
Successful exploitation could allow an attacker with appropriate privileges and user interaction to execute arbitrary OS commands via crafted project names in scripts generated for OpenStack RC file downloading. This could compromise confidentiality and integrity of the system with limited impact on availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid using untrusted or specially crafted project names when generating OpenStack RC file download scripts. Monitor OpenStack vendor advisories for updates and patches addressing this issue.
