  "title": "Unauthenticated stored cross-site scripting in Extendify",
  "summary": "Extendify for WordPress versions through 3.1.6 can store attacker-supplied script in global style content because a block-style field is not safely handled. An unauthenticated remote attacker may cause script to run in another visitor's browser when that visitor views affected content; exposure requires the vulnerable plugin and reachable global-styles REST handling.",
  "mitigation": "Disable Extendify until a vendor-supported update is available, or restrict unauthenticated access to the WordPress global-styles REST endpoints at the web server or WAF. Review affected pages and global style data for unauthorized changes before re-enabling the plugin.",
