high Tenable Self-Hosted Container Security Plugin ID 420663

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - v8n is a javascript validation library. Versions of v8n prior to 1.5.1 were found to have an inefficient
 regular expression complexity in the `lowercase()` and `uppercase()` regex which could lead to a denial of
 service attack. In testing of the `lowercase()` function a payload of 'a' + 'a'.repeat(i) + 'A' with 32
 leading characters took 29443 ms to execute. The same issue happens with uppercase(). Users are advised to
 upgrade. There are no known workarounds for this issue. (CVE-2022-35923)
