CVE-2026-36045: n/a
picoclaw versions up to and including 0.1.2 contain an OS command injection vulnerability in the ExecTool component. The vulnerability arises because the guardCommand() function uses an incomplete denylist of regular expressions to restrict shell command execution, allowing potentially malicious commands to be executed. This vulnerability has a high severity rating with a CVSS score of 7.3. No official patch or remediation guidance is currently available, and no known exploits have been reported in the wild.
AI Analysis
Technical Summary
CVE-2026-36045 affects picoclaw versions 0.1.2 and earlier due to an OS command injection vulnerability in the ExecTool component (pkg/tools/shell.go). The guardCommand() function attempts to prevent unauthorized shell command execution by applying a denylist of eight regular expressions; however, this denylist is incomplete, enabling attackers to bypass these restrictions and execute arbitrary OS commands. This vulnerability is classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command). The CVSS v3.1 base score is 7.3, indicating a high severity with network attack vector, low attack complexity, no privileges required, no user interaction, and impacts on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation of this vulnerability could allow an unauthenticated attacker to execute arbitrary operating system commands on the affected system, potentially leading to partial compromise of confidentiality, integrity, and availability. This could result in unauthorized data access, modification, or service disruption. However, no known active exploits have been reported to date.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting access to the vulnerable component and avoid running untrusted input through the ExecTool component. Monitor vendor channels for updates regarding patches or official mitigations.
