CVE-2026-57115 · Severity: medium · CVSS 6.5 · Published 2026-09-14

PraisonAI's SpiderTools component is used to scrape web pages and extract information. A vulnerability allows attackers to redirect users from legitimate URLs to internal services (like metadata endpoints) without proper validation, potentially exposing sensitive internal data that should be blocked from external access.

## Technical details

The vulnerability exists in SpiderTools.scrape_page, which validates only the initial URL but allows requests.Session.get to follow HTTP redirects automatically without revalidating the destination. An attacker can craft a public-facing URL that redirects to a private, loopback (127.0.0.1), link-local, or metadata address (e.g., 169.254.169.254). The response body from the redirected private service is then returned through scrape_page and its callers (extract_links, crawl, extract_text), allowing information disclosure from otherwise blocked services. The issue is fixed in praisonaiagents version 1.6.59, which presumably implements proper redirect validation against restricted address ranges.
