Repomix: attach_packed_output can bypass file-read secret scanning for supported local files

Published Jul 15, 2026 · Updated Jul 18, 2026 · Assigned by GitHub_M

Description

Repomix is a tool that packs repositories into AI-friendly files. Prior to 1.14.1, the Repomix MCP server attach_packed_output and read_repomix_output flow can register and read arbitrary local .json, .txt, .md, or .xml files without the file_system_read_file runSecretLint() safety check or Repomix packed-output validation, allowing MCP callers to bypass the local file-read secret-scanning boundary. This issue is fixed in version 1.14.1.
