Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

praisonaiagents versions 1.5.128 before 1.6.58 are affected. The web_crawl() function checks only the initial URL and follows redirects without rechecking them, so an attacker who can influence the URLs passed to it can make the host fetch loopback, private-network, or cloud metadata endpoints and receive their response bodies. Upgrade to praisonaiagents 1.6.58.
