Summary
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.
Risk Assessment
The risk involves potential leakage of sensitive data stored in local git repositories, including source code, passwords, and keys, which could lead to a security breach for the organization.
Recommendation
Immediately update repomix to a version that blocks file:// URLs in the isValidRemoteValue function, or temporarily disable the git clone endpoint until a patch is applied.
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-2026-49987High
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.
