CVE-2026-57126Public exploitNetwork attack vectorHinoki check available

Internal data disclosure via unresolved DNS hostnames

Published Sep 14, 2026 · Updated Sep 14, 2026

SSRF in PraisonAI before 1.6.59 allows remote authenticated users to read internal responses through agent web-fetch tools. SpiderTools._host_is_blocked evaluates only literal host encodings and treats any DNS name as allowed without resolving its addresses. The attacker must be able to supply a fetched URL to an enabled web tool or URL mention; a controlled hostname can route the request to loopback, private, link-local, or cloud-metadata services.
