praisonaiagents: SSRF guard validates literal IPs only and never resolves DNS

CVSS 3.1 8.5 HIGHCheck source for fixed versionsKEV status unknown

Original advisory

cve-program · CVE-2026-57126

Published

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, SpiderTools._validate_url calls _host_is_blocked, which checks literal host encodings but does not resolve DNS names before scrape_page, crawl, extract_links, extract_text, or URL-mention fetches connect. An attacker-controlled hostname resolving to a loopback, private, link-local, or cloud-metadata address therefore bypasses the SSRF policy without a rebinding race and can expose internal responses to the agent. This issue is fixed in praisonaiagents 1.6.58.
