node-opcua: Uncontrolled Resource Consumption
CVE-2022-24375 is a high-severity uncontrolled resource consumption vulnerability in node-opcua, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 2.74.0 as the first without the flaw, so updating node-opcua to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.72% chance of exploitation within 30 days, higher than 78% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update node-opcua to 2.74.0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
