Prior to 2.7.14, Deno&#8217;s permission system enforces filesystem and execution restrictions by comparing the requested path against the path supplied to &#8211;deny-read, &#8211;deny-write, &#8211;deny-run, or &#8211;deny-ffi. On macOS, that comparison was done at the raw-byte level while the APFS filesystem treats different Unicode spellings of the same name as the same file. That means a program could reach a denied path by spelling it differently than the deny rule. This vulnerability is fixed in 2.7.14.<\/p>\n<p>  Severity: 0.0 | NA<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-49401 Published : June 23, 2026, 5:22 p.m. | 21\u00a0minutes ago Description :Deno is a JavaScript, TypeScript, and WebAssembly runtime.
