SCA: security update for praisonai (GHSA-32vr-5gcf-3pw2)

critical Tenable Self-Hosted Container Security Plugin ID 440049

Description

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

 - PraisonAI is a multi-agent teams system. Prior to 4.5.115, the AgentService.loadAgentFromFile method uses
 the js-yaml library to parse YAML files without disabling dangerous tags (such as !!js/function and
 !!js/undefined). This allows an attacker to craft a malicious YAML file that, when parsed, executes
 arbitrary JavaScript code. An attacker can exploit this vulnerability by uploading a malicious agent
 definition file via the API endpoint, leading to remote code execution (RCE) on the server. This
 vulnerability is fixed in 4.5.115. (CVE-2026-39890)

Solution

Update the praisonai library and its related packages to version 4.5.115 or later.
