"The version of nodejs / nodejs18 / reaper installed on the remote CBL Mariner 2.0 host is prior to tested version. It
is, therefore, affected by a vulnerability as referenced in the CVE-2024-21538 advisory.

  - Versions of the package cross-spawn before 6.0.6, from 7.0.0 and before 7.0.5 are vulnerable to Regular
    Expression Denial of Service (ReDoS) due to improper input sanitization. An attacker can increase the CPU
    usage and crash the program by crafting a very large and well crafted string. (CVE-2024-21538)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
