Overview
Affected versions of this package are vulnerable to Incorrect Default Permissions in the futimes() function of lib/internal/fs/promises.js, which backs FileHandle.utimes() and performs no file system permission check. An attacker who can execute code in a process running under the Permission Model without write access can alter a file's access and modification timestamps, including on paths granted only read access through --allow-fs-read, by calling utimes() on a FileHandle. Exploitation requires the process to be started with the Permission Model enabled, and the impact is limited to changing file timestamps rather than file contents.
