CRITICAL 9.1REMOTE
CVE-2026-64863 is a critical-severity flaw (CVSS 9.1) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
goshs is a feature-rich single-binary file server for red teamers and developers. Prior to 2.1.4, the httpserver/server.go wdGuard handled WebDAV MOVE as a write-only method and did not enforce --no-delete, allowing WebDAV clients to delete or overwrite files via MOVE with Overwrite: T. This issue is fixed in version 2.1.4.
Why this priority
- Critical severity
- CISA SSVC: public proof of concept
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
