Security readout for executives and security teams
Plain-English summary
CVE-2026-25046 is a low-severity command injection issue in MoonshotAI kimi-agent-sdk development publish scripts. It affects repository maintainers or developers running those scripts, not users of the published VS Code extension. A maliciously named VSIX file could cause unintended commands to run during publishing.
Executive priority
Treat as low priority unless your organization builds or publishes from this repository. The main risk is compromise of developer or release environments, not customer systems. Patch during normal maintenance or before the next publishing activity.
Technical view
Before kimi-agent-sdk 0.1.6, vsix-publish.js and ovsx-publish.js passed filenames into execSync() as shell command strings. Filenames containing shell metacharacters could trigger command injection. The fix replaces execSync with execFileSync using array arguments. The vulnerable files are repository development scripts and are not included in the published VS Code extension.
Likely exposure
Exposure is limited to developers or release automation using the affected repository scripts before version 0.1.6. End users of the published VS Code extension are not affected, according to the advisory.
Exploitation context
The reported scenario requires local access or influence over VSIX filenames, high privileges, and user interaction to run the publish scripts. The source bundle indicates this is not in CISA KEV, and no cited source reports active exploitation.
Researcher notes
This is CWE-77 command injection with CVSS 2.9. Scope is narrow: development scripts only, pre-0.1.6, requiring a crafted filename and script execution. Avoid treating the VS Code extension as affected unless new evidence contradicts the advisory.
Mitigation direction
- Upgrade kimi-agent-sdk to version 0.1.6 or later.
- If upgrade is delayed, ensure VSIX filenames are safe before running publish scripts.
- Restrict who can add or rename VSIX files in release directories.
- Review release automation that runs repository publish scripts.
Validation and detection
- Confirm the repository or package version is 0.1.6 or later.
- Check whether vsix-publish.js or ovsx-publish.js are used in workflows.
- Verify publish scripts no longer call execSync with shell command strings.
- Confirm release directories do not contain unsafe VSIX filenames.

Improper Neutralization of Special Elements used in a Command ('Command Injection')
Improper Neutralization of Special Elements used in a Command ('Command Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
