CVE-2025-62719Public exploitNetwork attack vector

Authenticated internal network reconnaissance via unchecked URL

Published Nov 4, 2025 · Updated Nov 4, 2025

SSRF in Kovah LinkAce before 2.4.0 allows remote authenticated users to probe internal network services through keyword fetching. The htmlKeywordsFromUrl method in FetchController validates only URL syntax, then sends an HTTP GET without rejecting private, loopback, link-local, or reserved destinations. Any authenticated account can use POST /fetch/keywords-for-url for port scanning and service discovery, but returned data is limited to HTML meta keywords.
