SSRF in PraisonAI via Web Crawl Tool

Publication date: 2026-08-05

Last updated on: 2026-08-05

Assigner: GitHub, Inc.

Description
PraisonAI is a multi-agent teams system. In versions prior to 1.6.58, the web_crawl tool performs its SSRF check only on the initially supplied URL, allowing the protection to be bypassed so the tool connects to attacker-chosen internal destinations. The check resolves the hostname once with socket.gethostbyname and rejects private/loopback/link-local results, but then passes the URL to a fetcher using httpx.Client(follow_redirects=True) (or urllib.request.urlopen when httpx is absent, which also follows redirects) that re-resolves the hostname at connect time with no further validation. This validate-here/fetch-there gap is exploitable through both HTTP redirects and DNS rebinding. If an attacker can influence URLs passed to web_crawl(), directly or through an agent/tool workflow, they can cause the PraisonAI host to fetch loopback, private-network, or cloud metadata endpoints reachable from that host, with the response body returned in the web_crawl() result. This issue has been fixed in version 1.6.58.

CWE ID Description
CWE-918 The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
CWE-367 The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check.

Executive Summary

The vulnerability in PraisonAI versions before 1.6.58 involves the web_crawl tool performing SSRF checks only on the initial URL. The tool resolves the hostname once to block private or loopback addresses but then passes the URL to a fetcher that re-resolves the hostname during connection without further validation. This allows attackers to bypass protections via HTTP redirects or DNS rebinding, potentially accessing internal or cloud metadata endpoints from the host.

Detection Guidance

To detect this vulnerability, monitor network traffic for unexpected outbound connections from PraisonAI instances, especially to private or loopback addresses. Check logs for web_crawl tool usage with URLs that redirect to internal destinations. No specific commands are provided in the context.

Impact Analysis

An attacker could exploit this to make the PraisonAI host fetch sensitive internal endpoints or cloud metadata, exposing data or enabling further attacks. The host may return responses from these endpoints in the web_crawl result, potentially leaking confidential information.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles or HIPAA's confidentiality requirements. Organizations using affected versions may face compliance breaches due to potential data exposure.

Mitigation Strategies

Upgrade PraisonAI to version 1.6.58 or later to address the vulnerability. If upgrading is not immediately possible, restrict network access for PraisonAI instances to prevent outbound connections to internal or sensitive endpoints.
