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=./`. It's 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\u00a0`allow-write`\u00a0permission, however, when a file is opened, even with read only flags and deny-write permission, it's 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."}], "lastModified": "2025-10-16T18:12:40.397", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:deno:deno:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E75979F4-50DD-41E8-932A-C576F86DBFCF", "versionEndIncluding": "2.2.15"}, {"criteria": "cpe:2.3:a:deno:deno:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7DD66938-204A-4542-BA86-274BB232C8C9", "versionEndExcluding": "2.5.3", "versionStartIncluding": "2.3.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
