Stored XSS in Happy Monkey SCSS Happy Compiler 1.3.10 and earlier allows remote authenticated users to inject malicious scripts. The import_settings() function lacks a capability check and insufficiently sanitizes script-bearing input before storing imported settings. Subscriber-level access is sufficient to persist scripts that execute in browsers rendering the affected output.
