CVE-2023-49569Network attack vector

Remote code execution via ChrootOS path escape

Published Jan 12, 2024 · Updated Nov 14, 2024

Path traversal in go-git before 5.11.0 allows remote attackers to write arbitrary files through crafted Git server replies. ChrootOS handles paths from those replies without reliably confining resolved filesystem operations to its root. Exposure requires filesystem-backed ChrootOS, the default for PlainOpen and PlainClone; BoundOS and in-memory filesystems are unaffected, and file writes can lead to code execution.
