Vulnerability identifier: #VU82069

Vulnerability risk: Medium

CVSSv4.0: 1.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CWE-ID: CWE-354

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
Node.js
Server applications / Web servers

Vendor: Node.js Foundation

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to an error in the policy feature, which checks the integrity of a resource against a trusted manifest. An application can intercept the operation and return a forged checksum to node's policy implementation, thus effectively disabling the integrity check.

Mitigation
Install updates from vendor's website.
