CVE-2026-49987

HIGH Exploitation: PoC
7.5
CVSS 4.0
Description
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.
