[R1] Security Center Version 6.9.0 Fixes Multiple Vulnerabilities

Critical

Synopsis

Security Center leverages third-party software to help provide underlying functionality. Several of the third-party components (curl, underscoreJS) were found to contain vulnerabilities, and updated versions have been made available by the providers. 

Out of caution and in line with best practice, Tenable has opted to upgrade these libraries to address the potential impact of the issues. Security Center 6.9.0 updates the following components:

  • curl to version 8.20
  • underscoreJS to version 1.13.8

Additionally, several vulnerabilities were reported to Tenable and addressed within this update. Please see the full list of resolved issues below.
