Billy is an interface filesystem abstraction for Go. Prior to versions 5.9.0 and 6.0.0-alpha.1, multiple components may improperly handle crafted or malformed input, resulting in panics, infinite loops, uncontrolled recursion, or excessive resource consumption. These issues arise from insufficient validation and missing safety mechanisms such as cycle detection, recursion limits, or defensive handling of unexpected states when processing untrusted repository data and filesystem structures. This issue has been patched in versions 5.9.0 and 6.0.0-alpha.1.
