SCA: security update for PraisonAI, praisonaiagents (GHSA-5c6w-wwfq-7qqm)

medium Tenable Cloud Security Plugin ID 442547

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, `spider_tools` URL validation can be bypassed using alternate loopback host
 encodings. The tool contains a URL validation function intended to block local or unsafe targets before
 fetching attacker-controlled URLs. However, the validation only blocks a small set of exact host strings
 such as `localhost` and `127.0.0.1`. It does not normalize hostnames, resolve DNS, parse numeric IPv4
 variants, or validate the final resolved IP address before making the request. As a result, certain URLs
 may bypass the protection and still reach loopback services. After the weak validation passes,
 `scrape_page()` calls `requests.Session.get()` on the attacker-controlled URL. This allows an attacker who
 can influence URLs passed to `scrape_page`, `crawl`, or `extract_text` to induce SSRF requests against
 loopback-only services. This is a server-side request forgery protection bypass. PraisonAI version 4.6.40
 and praisonaiagents version 1.6.40 contain a patch. (CVE-2026-47390)

Solution

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