Deno is a JavaScript, TypeScript, and WebAssembly runtime. In versions prior to 2.5.3 and 2.2.15, Deno.FsFile.prototype.utime and Deno.FsFile.prototype.utimeSync are not limited by the permission model check --deny-write=./. Its possible to change to change the access (atime) and modification (mtime) times on the file stream resource even when the file is opened with read only permission (and write: false) and file write operations are not allowed (the script is executed with --deny-write=./). Similar APIs like Deno.utime and Deno.utimeSync require allow-write permission, however, when a file is opened, even with read only flags and deny-write permission, its still possible to change the access (atime) and modification (mtime) times, and thus bypass the permission model. Versions 2.5.3 and 2.2.15 fix the issue.

Weakness

A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.
