SCA: security update for PraisonAI, praisonaiagents (GHSA-5cxw-77wg-jrf3)

medium Tenable Cloud Security Plugin ID 442500

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 version 4.6.40 of PraisonAI, corresponding to version
 1.6.40 of praisonaiagents, PraisonAI's direct-prompt CLI automatically expands `@url:` mentions in raw
 prompt text before agent execution begins. If a prompt contains `@url:<http-or-https-url>`, the CLI calls
 `MentionsParser.process(...)`. The `@url:` handler then performs a direct `urllib.request.urlopen()`
 request to the attacker-controlled URL and returns the response body. That response body is prepended to
 the final model prompt context. There is no loopback/private-address restriction, no metadata-service
 restriction, and no approval gate before the fetch. As a result, attacker-influenced prompt text can cause
 the operator's machine to fetch localhost-only HTTP resources and inject the response into model context.
 PraisonAI version 4.6.40 and praisonaiagents version 1.6.40 contain a fix. (CVE-2026-47395)

Solution

Update the praisonaiagents library and its related packages to version 1.6.40 or later.
