Go to dashboardTwo issues in Node.js affect the 20.x, 22.x and 24.x release lines. A Windows device-name flaw (CON, PRN, AUX) can bypass path traversal protection in path.normalize() and path.join, and a V8 string hashing regression in 24.x re-enables hash collision denial of service.
Summary written from the sources below. Check the originals before acting.
First seen by InfraStack 2026-10-23 19:13 UTC. All times on this page are UTC.
Windows deployments are exposed to the path traversal flaw when user input reaches path.join or path.normalize, and Node.js 24.x deployments are exposed to the HashDoS flaw when attacker-controlled strings are hashed. Teams running only Linux or with no user-controlled paths or strings face lower risk but should still upgrade, since the sources say all users in active release lines are affected.

Commercial support for versions past the Maintenance LTS phase is available through our OpenJS Ecosystem Sustainability Program partners Tuesday, July 15, 2025 Security Releases TNJP The Node.js Project Tuesday, July 15, 2025 Security Releases Security releases available Updates are now available for the 24.x, 22.x, 20.x Node.js release lines for the following issues. Windows Device Names (CON, PRN, AUX) Bypass Path Traversal Protection in path.normalize() (CVE-2025-27210) - (high) An incomplete fix has been identified for CVE-2025-23084 in Node.js, specifically affecting Windows device names like CON, PRN, and AUX. This vulnerability affects Windows users of path.join API. Impact: This vulnerability affects all users in active release lines: 20.x, 22.x, 24.x Thank you, to oblivionsage for reporting this vulnerability and thank you RafaelGSS for fixing it. HashDoS in V8 (CVE-2025-27209) - (high) The V8 release used in Node.js v24.0.0 has changed how string hashes are computed using rapidhash. This implementation re-introduces the HashDoS vulnerability as an attacker who can control the strings to be hashed can generate many hash collisions - an attacker can generate collisions even without knowing the hash-seed. While the V8 team does not classify this as a security vulnerability, the Node.js project considers it one due to its potential impact in real-world scenarios. This vulnerability affects Node.js v24.x users. Impact: This vulnerability affects all users in active release lines: 24.x Thank you, to sharp_edged for reporting this vulnerability and thank you targos for fixing it. Downloads and release details Node.js v20.19.4 Node.js v22.17.1 Node.js v24.4.1 Summary The Node.js project will release new versions of the 24.x, 22.x, 20.x releases lines on or shortly after, Tuesday, July 15, 2025 in order to address: 2 high severity issues.
