SSRF in Jina AI Reader at commit 1574bfd380d249c86c82db4dace0d9c8fe17e2b1 allows remote attackers to read internal responses. The crawler's isValidTLD check accepts dotted IPv4 addresses with a final segment of at least two characters, and Puppeteer blocks only localhost and 127.* destinations. Network access to Reader requires no account and permits private-service discovery or response retrieval, including cloud instance metadata.
