CVE-2026-88624

Arbitrary directory deletion via unchecked worktree path

Published Sep 22, 2026 · Updated Sep 22, 2026

Path traversal in OpenCode 1.18.26 allows attackers to recursively delete arbitrary directories through a crafted worktree removal request. Worktree.remove canonicalizes the supplied directory but, when it is absent from Git's worktree list, passes the attacker-selected path to fs.rm with recursive and force enabled. Reachability requires access to the worktree-removal interface, and successful exploitation destroys files accessible to the OpenCode process.
