CVE-2026-55526 is a server-side request forgery vulnerability in PraisonAI and its praisonaiagents component before praisonaiagents 1.6.58 (and associated PraisonAI releases before 4.6.58). The hostname-blocking logic used by web-scraping functionality validated ordinary hostnames without resolving them before the HTTP request was made. An attacker-controlled hostname can therefore pass validation while resolving to a loopback, private, link-local, multicast, or other prohibited address. Version 1.6.58 resolves hostnames using socket.getaddrinfo and rejects DNS-resolution failures.

A server-side request forgery style vulnerability in PraisonAI/praisonaiagents where hostname validation fails to resolve ordinary hostnames before fetching, allowing crafted hostnames such as 127.0.0.1.nip.io to resolve to loopback and enable internal HTTP access.
A high-severity SSRF-like validation bypass in PraisonAI's praisonaiagents library that permits access to internal HTTP resources by using crafted hostnames that resolve to loopback addresses. Fixed in version 1.6.58 by resolving hostnames with socket.getaddrinfo and failing closed on DNS errors.
