Description

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.
