Summary
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.
Risk Assessment
The risk includes unauthorized access to internal network resources, leakage of sensitive data from cloud metadata services (e.g., GCP), and reading local system files, which could lead to privilege escalation or confidentiality breaches.
Recommendation
Immediately update repomix to a version that includes a fix for URL validation in the POST /api/pack endpoint. Until an update is available, restrict access to this endpoint using a firewall or authentication.
Other vulnerabilities in Repomix
See all- 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.
- 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.
