Last modified

CVE-2023-38552 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application can intercept the operation and return a forged checksum to the node's policy implementation, thus effectively disabling the integrity check. Impacts: This vulnerability affects all users using the experimental policy mechanism in all active release lines: 18.x and, 20.x. Please note that at the time this CVE was issued, the policy mechanism is an experimental feature of Node.js.. EPSS estimates a 1.11% chance of exploitation in the next 30 days.
