CVE-2026-49987
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk40th percentile - higher than 40% of all known CVEs
Summary
Repomix prior to version 1.14.1 contains a vulnerability in the execGitShallowClone function where the --remote-branch parameter is passed directly to git fetch and git checkout without validation or --end-of-options. This allows injection of Git options like --upload-pack, bypassing validateGitUrl() checks and enabling command execution via local or SSH transports.
Risk Assessment
An attacker can exploit this vulnerability to achieve remote code execution on the server, potentially leading to system compromise, data theft, or further attacks on the infrastructure.
Recommendation
Immediately upgrade Repomix to version 1.14.1 or later, which includes a fix that prevents Git option injection.
Other vulnerabilities in Repomix
See all- CVE-2026-59702Critical
Repomix contains a server-side request forgery (SSRF) vulnerability in the POST /api/pack endpoint that allows unauthenticated attackers to make arbitrary outbound requests. The endpoint fails to properly validate http://, https://, and file:// URLs before passing them to git clone, enabling attackers to access private network addresses, GCP metadata services, or local filesystem paths.
- CVE-2026-49988Medium
Repomix MCP server before version 1.14.1 allows registering and reading arbitrary local .json, .txt, .md, or .xml files without the file_system_read_file runSecretLint() safety check or Repomix packed-output validation. This enables MCP callers to bypass the local file-read secret-scanning boundary.
- CVE-2026-59703High
Repomix contains a local file inclusion vulnerability in the git clone endpoint that allows unauthenticated attackers to read arbitrary local git repositories. The isValidRemoteValue function in src/core/git/gitRemoteParse.ts fails to block file:// URLs, permitting attackers to supply file:// scheme URLs that bypass validation and are passed directly to git clone, enabling unauthorized access to all tracked file contents on the server filesystem.
Original NVD description (English source)
Repomix is a tool that packs repositories into AI-friendly files. Prior to 1.14.1, src/core/git/gitCommand.ts execGitShallowClone passes the --remote-branch value directly to git fetch and git checkout without validation or --end-of-options, allowing --upload-pack or other Git option injection that bypasses validateGitUrl() dangerous parameter checks and can execute commands through local or SSH-style transports. This issue is fixed in version 1.14.1.
