Detailsinfo

A vulnerability classified as problematic has been found in MoonshotAI kimi-agent-sdk up to 0.1.5. Affected is the function execSync of the file vsix-publish.js. The manipulation with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Kimi Agent SDK is a set of libraries that expose the Kimi Code (Kimi CLI) agent runtime in applications. The vsix-publish.js and ovsx-publish.js scripts pass filenames to execSync() as shell command strings. Prior to version 0.1.6, filenames containing shell metacharacters like $(cmd) could execute arbitrary commands. Note: This vulnerability exists only in the repository's development scripts. The published VSCode extension does not include these files and end users are not affected. This is fixed in version 0.1.6 by replacing execSync with execFileSync using array arguments. As a workaround, ensure .vsix files in the project directory have safe filenames before running publish scripts.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-25046 since 01/28/2026. The exploitability is told to be difficult. Local access is required to approach this attack. Additional levels of successful authentication are necessary for exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1202 by the MITRE ATT&CK project.

Upgrading to version 0.1.6 eliminates this vulnerability.
