According to WordPress, the plugin was eliminated from the plugin repository on Monday and is now unavailable for download. A protection researcher then “made the irresponsible and threatening selection to put up a weblog put together with an evidence of concept (POC) detailing how to take advantage of a set of two software vulnerabilities present within the plugin” – and then the exploits started, Wordfence researchers said. “We see a great extent of attempts to exploit this vulnerability,” researchers with Wordfence said in a Thursday submission outlining the exploits. “Site owners walking the Yellow Pencil Visual Theme Customizer plugin are entreated to take it away from their sites without delay.”
Vulnerabilities
Researchers stated that one of the two flaws within the plugin is a privilege-escalation vulnerability in its yellow pencil. Personal home page document.
