SCA: security update for pycti (GHSA-ffm6-vvph-g5f5)

high Tenable Cloud Security Plugin ID 443752

Description

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

 - OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. Prior
 to 6.8.16, the OpenCTI platform’s data ingestion feature accepts user-supplied URLs without validation and
 uses the Axios HTTP client with its default configuration (allowAbsoluteUrls: true). This allows attackers
 to craft requests to arbitrary endpoints, including internal services, because Axios will accept and
 process absolute URLs. This results in a semi-blind SSRF, as responses may not be fully visible but can
 still impact internal systems. This vulnerability is fixed in 6.8.16. (CVE-2026-21887)

Solution

Update the pycti library and its related packages to version 6.8.16 or later.
