What is CVE-2025-55132?
CVE-2025-55132 is a low-severity missing authorization vulnerability in Nodejs Node.js, published on 20 Jan 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
A flaw in Node.js's permission model allows a file's access and modification timestamps to be changed via `futimes()` even when the process has only read permissions. Unlike `utimes()`, `futimes()` does not apply the expected write-permission checks, which means file metadata can be modified in read-only directories. This behavior could be used to alter timestamps in ways that obscure activity, reducing the reliability of logs. This vulnerability affects users of the permission model on Node.js v20, v22, v24, and v25.
