CVE-2026-57126praisonaiagents: SSRF guard validates literal IPs only and never resolves DNS
High 8.5
In plain English
A high-severity server-side request forgery in PraisonAI from MervinPraison. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 32% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
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.
