CVE-2026-42853: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in apostrophecms @apostrophecms/cli
ApostropheCMS versions of the @apostrophecms/cli package up to and including 3.6.0 contain a command injection vulnerability in the 'apos create' command. This vulnerability arises because user input from the password prompt is directly embedded into a shell command without proper sanitization or escaping, allowing arbitrary command execution on the host system. No patched versions are currently available.
AI Analysis
Technical Summary
CVE-2026-42853 is an OS command injection vulnerability in the @apostrophecms/cli package (versions <=3.6.0). The vulnerability occurs in the 'apos create' command where user-supplied input from the password prompt is incorporated directly into a shell command without adequate neutralization of special characters. This improper input handling (CWE-78) enables an attacker with appropriate privileges to execute arbitrary commands on the host system. The CVSS 3.1 base score is 6.5, indicating a medium severity with high impact on confidentiality, integrity, and availability. As of the publication date, no official fix or patch is available.
Potential Impact
Successful exploitation allows an attacker with local privileges and user interaction to execute arbitrary OS commands on the host system, potentially leading to full compromise of confidentiality, integrity, and availability of the affected system. This can result in unauthorized access, data manipulation, or service disruption.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should avoid running the vulnerable 'apos create' command with untrusted input or in untrusted environments until a patch is released. Monitor the vendor's advisory channels for updates regarding remediation.
