CVE-2026-55526Public exploitNetwork attack vector

Internal HTTP response disclosure via unresolved hostnames

Published Aug 25, 2026 · Updated Aug 25, 2026

SSRF in PraisonAI before 4.6.58 and praisonaiagents before 1.6.58 allows remote authenticated users to read internal HTTP responses. spider_tools._host_is_blocked checks only literal addresses and aliases, then permits ordinary hostnames without resolving their destination IP addresses. Exploitation requires an enabled spider tool and control of a fetched URL; the resulting request can reach loopback, private-network, or metadata services.
