CVE-2026-57115: Mervinpraison Praisonai

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.59, SpiderTools.scrape_page validates only the initial URL and lets requests.Session.get follow redirects automatically, so a public-looking URL can redirect to a loopback, private, link-local, or metadata address without revalidation. The redirected response body is returned through scrape_page and its extract_links, crawl, and extract_text callers, allowing disclosure from otherwise blocked services. This issue is fixed in praisonaiagents 1.6.59.

Affected products

• Mervinpraison Praisonai: before 4.6.59 (fixed in 4.6.59)
• Mervinpraison Praisonaiagents: before 1.6.59 (fixed in 1.6.59)
