K-news plugin for WordPress before 1.1.1 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject script by supplying unsanitized input through the 'ff' parameter. Attackers can craft GET requests to /wp-content/plugins/knews/wysiwyg/fontpicker/index.php with malicious 'ff' values echoed into option tags to execute script and steal session cookies. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
